Person1: Alright , we need to have a plan here . First of all , which bed do you want ?
Person2:Well , everybody wants the bottom bunk . Why don't we flip a coin for it ?
Person1: Alright . Do you have a coin ?
Person2:Yes . Here's a quarter . I flip it , you call it in the air .
Person1: Heads .
Person2:Sorry , it's tails . You lose .
Person1: Oh , well . So you get the bottom bunk . What about our stereos ? It looks like we both brought our stereos . Probably we only have room for one .
Person2:Your stereo is better than mine . Do you mind if we use yours ?
Person1: No , I don't mind . I just don't know where we can put the speakers in this tiny room .
Person2:Probably we can put one on that counter . And we can put one on the floor by the bed . Over there .
Person1: Alright . That's a good plan . What about the desks ? We have two desks , one by the window and one by the door ? Which one do you want ?
Person2:Well , the desk by the window is nicer , of course . Don't you think ?
Person1: Yes , I agree .
Person2:So since I got the bottom bunk , why don't you get the desk by the window ? That would be more fair .
Person1: Alright .
Person2:I mean , we could flip a coin for it , but I would probably win again . I'm incredibly lucky you know . Especially with girls .
Person1: Is that right ?
Person2:Yes , that's right .
Person1: Well , I hope you let me hang out with you then . Maybe I can learn from you .
Person2:Oh , certainly . Certainly . I'm always willing to help beginners.Just call me Big Brother Dave .
Person1: Are all lucky people so stuck up ?
Person2:C'mon , don't take it seriously ! I'm just kidding .
Person1: Anyway , I get the desk by the window , you get the bottom bunk . That's it .
Person2:Why don't we start unpacking these boxes ?
Person1: I will go get something to eat . You unpack first.Then , when I come back , I'll unpack .
Person2:Alright . See you later .

Person1: Oh man ! I ' Ve been starving myself for days now and I haven ' t lost an ounce !
Person2:Are you trying to lose weight ?
Person1: Yeah , my friend is getting married next month and I ' m supposed to be a bridesmaid . I have to fit into my dress and look nice for her wedding , but I haven ' t lost any weight ! Look at these love handles .
Person2:You don ' t have to starve yourself to lose weight . I think that ' s where you ' re going wrong .
Person1: Why ? If I eat less , then my body will start eating away at my fat reserves , right ?
Person2:Not really . You should try to not eat foods high in calories , salts or saturated fats . Stay away from oily food and artificial flavors .
Person1: So you are saying that I should eat , but I should just watch what I eat ?
Person2:Yes ! You can also try to reduce your intake of carbohydrates and foods that are high in cholesterol . You can have steamed veggies or increase your protein intake found in chicken or fish .
Person1: If I do all this do you think I can lose twenty pounds in four weeks ?
Person2:Don ' t count on it .
