WEBVTT FILE 1 00:00:05.440 --> 00:00:07.839 there must be something 2 00:00:07.839 --> 00:00:10.639 i could watch 3 00:00:10.639 --> 00:00:12.240 must be 4 00:00:12.240 --> 00:00:13.840 oh hi 5 00:00:13.840 --> 00:00:15.599 james 6 00:00:15.599 --> 00:00:17.359 i was just looking at the paper because 7 00:00:17.359 --> 00:00:19.359 we have a festival in toronto called 8 00:00:19.359 --> 00:00:20.239 tiff 9 00:00:20.239 --> 00:00:22.160 toronto international film festival 10 00:00:22.160 --> 00:00:23.920 something like that happens every year 11 00:00:23.920 --> 00:00:25.920 and they always have these great movies 12 00:00:25.920 --> 00:00:27.680 but i usually find it difficult to find 13 00:00:27.680 --> 00:00:29.119 something and this year i thought i must 14 00:00:29.119 --> 00:00:30.960 go and see the festival 15 00:00:30.960 --> 00:00:32.239 and there must be something i could 16 00:00:32.239 --> 00:00:35.040 watch and if i miss it you know i must 17 00:00:35.040 --> 00:00:36.559 not miss it this year that's that's what 18 00:00:36.559 --> 00:00:38.000 i was thinking and when i thought of 19 00:00:38.000 --> 00:00:39.360 that i thought of you that's right i 20 00:00:39.360 --> 00:00:41.040 thought of you because i thought you 21 00:00:41.040 --> 00:00:43.120 probably want to know why we use must in 22 00:00:43.120 --> 00:00:44.640 so many different ways and they're 23 00:00:44.640 --> 00:00:45.760 different 24 00:00:45.760 --> 00:00:48.000 so i came up with something 25 00:00:48.000 --> 00:00:49.360 well 26 00:00:49.360 --> 00:00:50.879 let's talk to mystery he came up with 27 00:00:50.879 --> 00:00:53.039 something say that must be a new watch 28 00:00:53.039 --> 00:00:54.960 because you haven't been wearing one 29 00:00:54.960 --> 00:00:56.000 hmm 30 00:00:56.000 --> 00:00:57.600 what do we mean well let's look over 31 00:00:57.600 --> 00:00:58.399 here 32 00:00:58.399 --> 00:00:59.680 must 33 00:00:59.680 --> 00:01:01.600 must actually isn't what you think it is 34 00:01:01.600 --> 00:01:04.479 must means this 35 00:01:04.479 --> 00:01:07.920 dot u dot s dot t 36 00:01:07.920 --> 00:01:12.119 huh well it's 37 00:01:19.520 --> 00:01:21.200 actually not understand 38 00:01:21.200 --> 00:01:23.520 hold on a second 39 00:01:23.520 --> 00:01:27.799 must and then we put this here 40 00:01:46.479 --> 00:01:49.200 must actually to me is a big sentence of 41 00:01:49.200 --> 00:01:51.520 must be understood as a statement of 42 00:01:51.520 --> 00:01:53.680 truth when we say must someone's trying 43 00:01:53.680 --> 00:01:56.560 to tell you something is true 44 00:01:56.560 --> 00:01:59.280 okay now from that something is true 45 00:01:59.280 --> 00:02:01.600 comes all of this information 46 00:02:01.600 --> 00:02:02.880 let me give you the first one let's look 47 00:02:02.880 --> 00:02:05.439 at number one 48 00:02:05.439 --> 00:02:07.280 logical conclusion 49 00:02:07.280 --> 00:02:09.599 well must be understood as statement of 50 00:02:09.599 --> 00:02:12.639 truth now we did must if you noticed 51 00:02:12.639 --> 00:02:14.639 now if we look at b 52 00:02:14.639 --> 00:02:16.720 we say because we usually say in english 53 00:02:16.720 --> 00:02:18.080 must 54 00:02:18.080 --> 00:02:19.040 be 55 00:02:19.040 --> 00:02:22.639 mr e must be wearing a new watch 56 00:02:22.639 --> 00:02:25.280 because i've never seen it before 57 00:02:25.280 --> 00:02:27.599 an example would be this because b here 58 00:02:27.599 --> 00:02:30.239 stands for 59 00:02:30.879 --> 00:02:32.160 believe 60 00:02:32.160 --> 00:02:34.319 so i must understand something is a 61 00:02:34.319 --> 00:02:36.080 statement of truth and i believe it's 62 00:02:36.080 --> 00:02:36.959 true 63 00:02:36.959 --> 00:02:39.120 cool all right so we go for our first 64 00:02:39.120 --> 00:02:41.200 example so we got believe 65 00:02:41.200 --> 00:02:43.599 and i would say it must be a new watch 66 00:02:43.599 --> 00:02:45.040 why did i say that 67 00:02:45.040 --> 00:02:46.639 number one 68 00:02:46.639 --> 00:02:48.400 i 69 00:02:48.400 --> 00:02:51.840 have not seen 70 00:02:51.840 --> 00:02:53.599 it before 71 00:02:53.599 --> 00:02:56.720 okay that's number one 72 00:02:56.959 --> 00:02:58.319 number two 73 00:02:58.319 --> 00:02:59.280 okay 74 00:02:59.280 --> 00:03:01.280 um well it doesn't have to be new i 75 00:03:01.280 --> 00:03:03.519 haven't seen it before but 76 00:03:03.519 --> 00:03:05.840 he 77 00:03:06.480 --> 00:03:08.239 doesn't 78 00:03:08.239 --> 00:03:10.000 have 79 00:03:10.000 --> 00:03:12.319 a watch 80 00:03:12.319 --> 00:03:14.480 so if i know he doesn't have a watch and 81 00:03:14.480 --> 00:03:16.560 i have not seen this watch before i 82 00:03:16.560 --> 00:03:19.800 would say 83 00:03:19.919 --> 00:03:22.319 that's very fancy english for therefore 84 00:03:22.319 --> 00:03:23.840 see therefore 85 00:03:23.840 --> 00:03:26.080 okay 86 00:03:29.440 --> 00:03:31.120 okay 87 00:03:31.120 --> 00:03:33.360 it must be new so what i'm saying here 88 00:03:33.360 --> 00:03:35.040 is 89 00:03:35.040 --> 00:03:37.120 fact one i've never seen it before fact 90 00:03:37.120 --> 00:03:40.319 two he doesn't wanna watch so conclusion 91 00:03:40.319 --> 00:03:42.640 or logical conclusion 92 00:03:42.640 --> 00:03:45.040 it must be a new watch 93 00:03:45.040 --> 00:03:46.879 cool all right and that comes from 94 00:03:46.879 --> 00:03:48.560 remember what i said must be understood 95 00:03:48.560 --> 00:03:50.400 as a statement of truth 96 00:03:50.400 --> 00:03:52.959 now here's the key thing just because 97 00:03:52.959 --> 00:03:55.439 i've done this and in this case it might 98 00:03:55.439 --> 00:03:57.920 be true it might not be maybe mr e bar 99 00:03:57.920 --> 00:04:00.319 the watch from his brother right maybe 100 00:04:00.319 --> 00:04:01.680 he got born he goes that's cool can i 101 00:04:01.680 --> 00:04:03.840 borrow it for today it's not new it's an 102 00:04:03.840 --> 00:04:05.599 old watch and he still doesn't have a 103 00:04:05.599 --> 00:04:06.560 watch 104 00:04:06.560 --> 00:04:07.840 and it's but it's only true i haven't 105 00:04:07.840 --> 00:04:10.000 seen it before that doesn't necessarily 106 00:04:10.000 --> 00:04:11.840 make it true 107 00:04:11.840 --> 00:04:14.080 okay so when we say it is what i believe 108 00:04:14.080 --> 00:04:15.280 to be true and that's what you must 109 00:04:15.280 --> 00:04:17.040 understand here and that's the key to 110 00:04:17.040 --> 00:04:18.320 must be 111 00:04:18.320 --> 00:04:20.479 the key is believe and that's why we get 112 00:04:20.479 --> 00:04:22.240 a logical conclusion if the facts are 113 00:04:22.240 --> 00:04:24.720 true then this must be true now this is 114 00:04:24.720 --> 00:04:27.360 true in the present tense now we can 115 00:04:27.360 --> 00:04:29.120 also talk about this in the future tense 116 00:04:29.120 --> 00:04:33.000 like you must be 117 00:04:44.000 --> 00:04:45.360 so we can talk him in a future sense you 118 00:04:45.360 --> 00:04:46.800 must be leaving soon 119 00:04:46.800 --> 00:04:48.320 why because you have to be home by eight 120 00:04:48.320 --> 00:04:50.800 o'clock it's now 7 30 it's also getting 121 00:04:50.800 --> 00:04:52.479 dark and you have to drive so you must 122 00:04:52.479 --> 00:04:54.080 be leaving soon right 123 00:04:54.080 --> 00:04:56.880 logical conclusion now if i want to say 124 00:04:56.880 --> 00:04:58.800 something about it in the past i have to 125 00:04:58.800 --> 00:05:01.120 change it just so slightly 126 00:05:01.120 --> 00:05:03.360 now 127 00:05:04.400 --> 00:05:06.560 i want to use this term if i want to say 128 00:05:06.560 --> 00:05:08.400 this in the past okay so we did future i 129 00:05:08.400 --> 00:05:10.479 just showed that but if i want to say 130 00:05:10.479 --> 00:05:12.320 post i'm going to do something here i'm 131 00:05:12.320 --> 00:05:13.279 going to add 132 00:05:13.279 --> 00:05:14.880 have 133 00:05:14.880 --> 00:05:17.199 okay 134 00:05:18.320 --> 00:05:19.600 i've talked about this before in other 135 00:05:19.600 --> 00:05:20.720 lessons so you might want to go check 136 00:05:20.720 --> 00:05:22.800 them out where i talk about have and 137 00:05:22.800 --> 00:05:25.839 modal use or it's perfect use have is 138 00:05:25.839 --> 00:05:27.759 usually a connector it connects things 139 00:05:27.759 --> 00:05:29.520 that's what i say it can have means in 140 00:05:29.520 --> 00:05:32.479 this case you must have been 141 00:05:32.479 --> 00:05:34.560 so by adding have i have to use a past 142 00:05:34.560 --> 00:05:37.198 participle 143 00:05:37.440 --> 00:05:39.520 verb in this past participle form that 144 00:05:39.520 --> 00:05:41.680 tells me it's in the past 145 00:05:41.680 --> 00:05:44.000 so if i say you must have been tired 146 00:05:44.000 --> 00:05:45.279 yesterday 147 00:05:45.279 --> 00:05:48.080 okay i'm actually saying i believe 148 00:05:48.080 --> 00:05:49.839 because that's good must have in the 149 00:05:49.839 --> 00:05:52.160 past yesterday you were tired so you 150 00:05:52.160 --> 00:05:55.280 must have been tired 151 00:05:55.440 --> 00:05:57.360 yesterday 152 00:05:57.360 --> 00:06:00.400 now once again i could do something like 153 00:06:00.400 --> 00:06:02.479 because you worked a lot you didn't eat 154 00:06:02.479 --> 00:06:04.800 a lot and you didn't get any sleep 155 00:06:04.800 --> 00:06:07.120 therefore you must have been tired 156 00:06:07.120 --> 00:06:10.000 yesterday not today cool all right 157 00:06:10.000 --> 00:06:12.240 so we've shown how we can use must be to 158 00:06:12.240 --> 00:06:14.160 show something is what someone believes 159 00:06:14.160 --> 00:06:15.839 to be true 160 00:06:15.839 --> 00:06:16.960 in the past 161 00:06:16.960 --> 00:06:20.319 in the present and in the future now 162 00:06:20.319 --> 00:06:21.600 you're probably thinking well that's all 163 00:06:21.600 --> 00:06:23.520 nice but why do sometimes people say you 164 00:06:23.520 --> 00:06:25.440 must not be 165 00:06:25.440 --> 00:06:27.360 it's still what i think is true but we 166 00:06:27.360 --> 00:06:30.160 call that sort of like a negative proof 167 00:06:30.160 --> 00:06:32.000 what do i mean by negative proof so 168 00:06:32.000 --> 00:06:34.479 let's add that in there okay so i'm 169 00:06:34.479 --> 00:06:36.720 still going to say it's believe 170 00:06:36.720 --> 00:06:38.560 so you still believe something even 171 00:06:38.560 --> 00:06:39.759 though you say not because normally you 172 00:06:39.759 --> 00:06:42.560 say not you mean no 173 00:06:44.080 --> 00:06:45.520 okay normally that's what happens you 174 00:06:45.520 --> 00:06:49.199 say not no but it's a negative proof 175 00:06:49.199 --> 00:06:51.440 um give you an example 176 00:06:51.440 --> 00:06:54.440 um 177 00:07:03.520 --> 00:07:04.720 no no i want to put that because that's 178 00:07:04.720 --> 00:07:06.720 in past okay 179 00:07:06.720 --> 00:07:10.319 let's go like this for you okay mr e 180 00:07:10.319 --> 00:07:11.360 okay 181 00:07:11.360 --> 00:07:12.720 has 182 00:07:12.720 --> 00:07:14.840 no 183 00:07:14.840 --> 00:07:17.280 job okay 184 00:07:17.280 --> 00:07:19.680 mystery 185 00:07:19.680 --> 00:07:22.000 um 186 00:07:22.080 --> 00:07:23.759 has 187 00:07:23.759 --> 00:07:24.880 no 188 00:07:24.880 --> 00:07:26.639 money 189 00:07:26.639 --> 00:07:28.080 then you might say 190 00:07:28.080 --> 00:07:30.240 therefore 191 00:07:30.240 --> 00:07:32.960 mr e 192 00:07:32.960 --> 00:07:35.680 must not 193 00:07:37.280 --> 00:07:38.160 be 194 00:07:38.160 --> 00:07:40.240 happy 195 00:07:40.240 --> 00:07:42.560 okay 196 00:07:43.199 --> 00:07:44.800 okay so in this case we're saying it's a 197 00:07:44.800 --> 00:07:46.080 negative proof saying yes i believe 198 00:07:46.080 --> 00:07:48.160 something is true but in a negative 199 00:07:48.160 --> 00:07:50.879 sense not a positive sense right because 200 00:07:50.879 --> 00:07:52.479 otherwise i would have to say mr e must 201 00:07:52.479 --> 00:07:54.960 be unhappy which is just flipping this 202 00:07:54.960 --> 00:07:57.280 this position of the adjective okay so 203 00:07:57.280 --> 00:07:59.039 that's why here must not be it's 204 00:07:59.039 --> 00:08:00.000 basically 205 00:08:00.000 --> 00:08:02.479 strong a strong belief in something 206 00:08:02.479 --> 00:08:04.720 right but in a negative way of saying it 207 00:08:04.720 --> 00:08:06.319 cool so we've done 208 00:08:06.319 --> 00:08:08.479 the positive must be we've done the 209 00:08:08.479 --> 00:08:10.720 negative must not be we've done the past 210 00:08:10.720 --> 00:08:12.879 must have been so why don't we look down 211 00:08:12.879 --> 00:08:14.240 to here 212 00:08:14.240 --> 00:08:15.599 as i said to you it's funny how we go 213 00:08:15.599 --> 00:08:17.520 from something you believe to something 214 00:08:17.520 --> 00:08:20.080 that's absolutely necessary necessity 215 00:08:20.080 --> 00:08:22.319 okay so then we go from here the next 216 00:08:22.319 --> 00:08:24.479 step was go must remember what we said 217 00:08:24.479 --> 00:08:27.120 must be understood as something as a 218 00:08:27.120 --> 00:08:29.919 statement of truth right we look at this 219 00:08:29.919 --> 00:08:30.879 strong 220 00:08:30.879 --> 00:08:33.679 recommendation 221 00:08:33.679 --> 00:08:36.000 by the way something before i forget 222 00:08:36.000 --> 00:08:38.320 when we say must hear i said we always 223 00:08:38.320 --> 00:08:40.640 say must be 224 00:08:40.640 --> 00:08:42.880 that's not necessarily true that's not 225 00:08:42.880 --> 00:08:45.120 necessarily true because sometimes when 226 00:08:45.120 --> 00:08:47.040 we say that 227 00:08:47.040 --> 00:08:49.519 i don't mean something must be i can say 228 00:08:49.519 --> 00:08:50.399 must 229 00:08:50.399 --> 00:08:52.240 like for instance 230 00:08:52.240 --> 00:08:55.360 must like and what i mean by that is you 231 00:08:55.360 --> 00:08:57.120 must like ice cream because you buy it 232 00:08:57.120 --> 00:08:58.240 all the time 233 00:08:58.240 --> 00:08:59.839 you offer it to your friends and it's 234 00:08:59.839 --> 00:09:01.440 always in your house you must like ice 235 00:09:01.440 --> 00:09:04.399 cream in this case it's still believe 236 00:09:04.399 --> 00:09:06.000 but i'm just going straight here that 237 00:09:06.000 --> 00:09:07.839 something must be a statement of truth 238 00:09:07.839 --> 00:09:09.440 and i don't have to put believe it's 239 00:09:09.440 --> 00:09:12.000 understood to be believed okay 240 00:09:12.000 --> 00:09:13.279 so sometimes when you see it like that 241 00:09:13.279 --> 00:09:14.800 you have to look for context because 242 00:09:14.800 --> 00:09:16.800 context is everything 243 00:09:16.800 --> 00:09:18.640 and in this case we're saying i believe 244 00:09:18.640 --> 00:09:20.640 still all right cool 245 00:09:20.640 --> 00:09:23.519 next one a strong recommendation well 246 00:09:23.519 --> 00:09:25.679 we're talking about must is here 247 00:09:25.679 --> 00:09:26.880 and we're going to look at strong 248 00:09:26.880 --> 00:09:28.958 recommendation what would that mean well 249 00:09:28.958 --> 00:09:31.440 once you believe something's true 250 00:09:31.440 --> 00:09:33.519 then you might recommend it to somebody 251 00:09:33.519 --> 00:09:34.559 and this is going to be interesting 252 00:09:34.559 --> 00:09:36.480 because here you notice i have must if 253 00:09:36.480 --> 00:09:37.920 you notice here i have should because in 254 00:09:37.920 --> 00:09:39.600 north america we usually say when 255 00:09:39.600 --> 00:09:41.040 something's right or the best thing to 256 00:09:41.040 --> 00:09:43.600 do you should do it in england and 257 00:09:43.600 --> 00:09:45.519 canada we also say you must do it but we 258 00:09:45.519 --> 00:09:47.760 mean it as a strong recommendation 259 00:09:47.760 --> 00:09:50.559 for instance ladies you're going out you 260 00:09:50.559 --> 00:09:52.720 see some beautiful shoes 261 00:09:52.720 --> 00:09:53.760 not mine 262 00:09:53.760 --> 00:09:55.519 they don't smell like roses but you know 263 00:09:55.519 --> 00:09:57.120 you get the drift and i don't mean the 264 00:09:57.120 --> 00:09:59.440 scent of my shoe okay 265 00:09:59.440 --> 00:10:00.800 now 266 00:10:00.800 --> 00:10:02.320 you see those shoes and you say to your 267 00:10:02.320 --> 00:10:04.320 best friend of course your girlfriend 268 00:10:04.320 --> 00:10:06.320 girl you see them shoes you must buy 269 00:10:06.320 --> 00:10:09.200 them okay 270 00:10:10.958 --> 00:10:12.480 must buy them 271 00:10:12.480 --> 00:10:13.440 okay 272 00:10:13.440 --> 00:10:16.480 now when we're saying that 273 00:10:17.519 --> 00:10:19.920 basically you're saying hey look 274 00:10:19.920 --> 00:10:22.078 i believe this is a good deal it's 275 00:10:22.078 --> 00:10:23.679 assumed that's why we don't put the b on 276 00:10:23.679 --> 00:10:25.040 the end it's assumed you understand the 277 00:10:25.040 --> 00:10:26.800 logic behind it you see the price you 278 00:10:26.800 --> 00:10:29.679 see the normal price so you go i believe 279 00:10:29.679 --> 00:10:31.360 this is a good price and i ought to do 280 00:10:31.360 --> 00:10:33.120 it or i should do it now 281 00:10:33.120 --> 00:10:34.399 should 282 00:10:34.399 --> 00:10:36.880 cool now when we say this it can you 283 00:10:36.880 --> 00:10:39.040 like you must go to see this movie it's 284 00:10:39.040 --> 00:10:41.200 an amazing 285 00:10:41.200 --> 00:10:43.040 must it's a strong recommendation for 286 00:10:43.040 --> 00:10:44.720 the movie right and that's going to be a 287 00:10:44.720 --> 00:10:46.320 future sense because you're not going to 288 00:10:46.320 --> 00:10:47.760 see the movie now i know you're not 289 00:10:47.760 --> 00:10:49.040 because i'm telling you about it but 290 00:10:49.040 --> 00:10:50.720 maybe in five minutes but when i say you 291 00:10:50.720 --> 00:10:52.640 must buy those shoes i want you to do it 292 00:10:52.640 --> 00:10:54.000 now buy them now because it's a good 293 00:10:54.000 --> 00:10:56.320 deal now okay and remember in north 294 00:10:56.320 --> 00:10:58.000 america we can also say should you 295 00:10:58.000 --> 00:10:59.360 should buy it or you should see the 296 00:10:59.360 --> 00:11:00.800 movie and that's our strong 297 00:11:00.800 --> 00:11:02.720 recommendation for the best thing to do 298 00:11:02.720 --> 00:11:03.760 cool 299 00:11:03.760 --> 00:11:04.800 brilliant 300 00:11:04.800 --> 00:11:07.040 now 301 00:11:07.040 --> 00:11:09.760 see i could say this 302 00:11:09.760 --> 00:11:12.720 i could say this as well 303 00:11:12.958 --> 00:11:14.240 but you know the truth of the matter is 304 00:11:14.240 --> 00:11:15.679 when you say you must buy them they're 305 00:11:15.679 --> 00:11:17.279 more there's more of an immediate see to 306 00:11:17.279 --> 00:11:18.480 it there's more of it you got to do it 307 00:11:18.480 --> 00:11:20.240 you got to do it now do it immediately 308 00:11:20.240 --> 00:11:21.920 as soon as you can when you should it's 309 00:11:21.920 --> 00:11:23.200 like 310 00:11:23.200 --> 00:11:25.519 i want to pontificate pontificate is a 311 00:11:25.519 --> 00:11:27.679 really fancy word for think about it but 312 00:11:27.679 --> 00:11:29.440 when someone says must 313 00:11:29.440 --> 00:11:30.720 ah 314 00:11:30.720 --> 00:11:33.679 do it do it now so it's like must 315 00:11:33.679 --> 00:11:35.760 powerful all right 316 00:11:35.760 --> 00:11:38.640 cool great 317 00:11:39.360 --> 00:11:42.480 we've gone from it's 318 00:11:42.480 --> 00:11:44.160 it's logical captain 319 00:11:44.160 --> 00:11:46.640 star trek it's just logical makes sense 320 00:11:46.640 --> 00:11:49.360 two i strongly recommend it 321 00:11:49.360 --> 00:11:51.040 the next one we're going to necessity 322 00:11:51.040 --> 00:11:53.040 and prohibition they're like two sides 323 00:11:53.040 --> 00:11:54.559 of a coin 324 00:11:54.559 --> 00:11:56.240 okay 325 00:11:56.240 --> 00:11:58.720 if mr e was a coin one side would be the 326 00:11:58.720 --> 00:12:00.078 head 327 00:12:00.078 --> 00:12:02.160 and one side would be the tail 328 00:12:02.160 --> 00:12:05.120 get it heads and tail why because when 329 00:12:05.120 --> 00:12:06.639 something's a necessary necessity 330 00:12:06.639 --> 00:12:08.480 sometimes the actual opposite would be a 331 00:12:08.480 --> 00:12:10.320 prohibition you must do this and you 332 00:12:10.320 --> 00:12:12.800 must not do this for instance you must 333 00:12:12.800 --> 00:12:13.760 study 334 00:12:13.760 --> 00:12:16.720 or you must not fail to study right 335 00:12:16.720 --> 00:12:20.240 opposite of the coin one is saying 336 00:12:20.240 --> 00:12:22.480 do not forget to do this and this is 337 00:12:22.480 --> 00:12:24.720 saying you must act now 338 00:12:24.720 --> 00:12:26.800 okay just opposite sides but what's 339 00:12:26.800 --> 00:12:29.120 interesting about it is this 340 00:12:29.120 --> 00:12:30.880 okay 341 00:12:30.880 --> 00:12:33.440 you notice this one has a past tense 342 00:12:33.440 --> 00:12:34.800 if you want to do past tense for this 343 00:12:34.800 --> 00:12:36.720 one it's only for necessity there is no 344 00:12:36.720 --> 00:12:39.040 past tense for prohibition 345 00:12:39.040 --> 00:12:40.480 what am i talking about well let's go to 346 00:12:40.480 --> 00:12:42.320 look first necessity 347 00:12:42.320 --> 00:12:44.240 these three go right in line first you 348 00:12:44.240 --> 00:12:46.000 make it's logical then you say i 349 00:12:46.000 --> 00:12:47.519 recommend it and then afterwards you say 350 00:12:47.519 --> 00:12:49.200 you know what just do it 351 00:12:49.200 --> 00:12:53.639 okay so we say you must 352 00:13:00.399 --> 00:13:01.360 okay 353 00:13:01.360 --> 00:13:03.200 so if ezekiel's thinking about this you 354 00:13:03.200 --> 00:13:06.200 must 355 00:13:07.519 --> 00:13:09.440 okay someone's gonna kill you you must 356 00:13:09.440 --> 00:13:10.958 kill him first 357 00:13:10.958 --> 00:13:12.880 okay because if you don't kill him first 358 00:13:12.880 --> 00:13:15.279 he'll kill you it's necessity you have 359 00:13:15.279 --> 00:13:17.519 no choice 360 00:13:17.519 --> 00:13:19.200 you have no choice you can't say it like 361 00:13:19.200 --> 00:13:20.480 had to kill him 362 00:13:20.480 --> 00:13:22.720 that was i must i must have not in this 363 00:13:22.720 --> 00:13:24.000 sense in this case it must must 364 00:13:24.000 --> 00:13:26.240 absolutely if you don't do it you're 365 00:13:26.240 --> 00:13:27.440 dead 366 00:13:27.440 --> 00:13:28.880 in english if we want to say the past 367 00:13:28.880 --> 00:13:30.480 the only way to do that is funny enough 368 00:13:30.480 --> 00:13:33.360 is to change it to had to 369 00:13:33.360 --> 00:13:35.519 i had to do it you have to do it or had 370 00:13:35.519 --> 00:13:37.600 to do it okay prohibition on the other 371 00:13:37.600 --> 00:13:40.078 hand is when we say must not you're not 372 00:13:40.078 --> 00:13:41.760 allowed to you have no permission you 373 00:13:41.760 --> 00:13:44.720 cannot do it okay that's the prohibition 374 00:13:44.720 --> 00:13:46.399 and in saying that 375 00:13:46.399 --> 00:13:48.160 we usually use this for the near future 376 00:13:48.160 --> 00:13:49.440 you must not forget to take your 377 00:13:49.440 --> 00:13:51.760 medicine you must not so we'll put that 378 00:13:51.760 --> 00:13:53.199 one up there okay 379 00:13:53.199 --> 00:13:54.720 must 380 00:13:54.720 --> 00:13:56.559 not sorry 381 00:13:56.559 --> 00:13:59.958 not forget 382 00:14:02.399 --> 00:14:03.679 right 383 00:14:03.679 --> 00:14:06.799 now that's near future 384 00:14:07.199 --> 00:14:09.040 generally what we use for near future 385 00:14:09.040 --> 00:14:10.639 another way of saying that would be have 386 00:14:10.639 --> 00:14:12.958 to now i think i've gone on for a long 387 00:14:12.958 --> 00:14:14.800 time and i must not
