Replying to Brothers rommate got owned

So I was at my brothers university today, and he lives in a dorm with 4 other people and theres this one guy from Sri lanka, all he does is watch movies, he doesnt own a single textbook and doesnt go to class unless its after 11 am. Hes smart as hell, and does his math tests without a calculator and still pulls off 85's. So we were sitting in the common area with the kitchen and what not and i was like is anyone else here?  And hes like no... oh wait maybe ranwall (the guy from sri lankas name, idd if thats how its spelt but thats the pronunciation)is here. Lol what a name. anyways i was like where is here. And my brothers like idk maybe in his room. So he goes and chacks and comes back 30 seconds later and was like yea hes smoking weed. so i said wtf why cant i smell it? and my brother goes, well he has his windows open and 3 fans blowing it out the window. So we continue to play xbox for like 29 minutes then the floor RA comes bashing thru the door. and he goes whos smoking weed. and we were both like what? (cause u couldnt smell it) so he walks into the guys room and catches him. Turns out the fans were blowing the smoke out of his window right into the RA's room. So the guy gets a week suspension, and flies out to live with his dad in New York for the week. His dads and broker on wall street. Some punishment huh?
