W: I’m so worried about Mark these days. Ever since he moved into his apartment, he has been losing weight. He really doesn’t look well at all.
M: He should try to gain some weight. He is probably not eating enough.
W: Well, anyway, how is Tim these days?
M: Tim? Oh, Tim has been worried, too. He is really getting much too fat. He needs to lose about 75 pounds now.
W: That’s a lot of weight to lose. What does Tim eat?
M: I really don’t know. But I am sure he is eating too much cake and candy.
W: Well, did I tell you Mark doesn’t eat any meat now? He only eats vegetables and fruit.
M: That’s probably why he is so thin. Does he smoke?
W: Does he smoke? About two packs of cigarettes a day. That’s my son, a smoking vegetarian.
M: En, if he stops smoking, he would gain weight. I know he would. Tim put on a lot of weight when he stopped smoking.
W: Does Tim play any sports?
M: Play sports? Oh. my! I keep telling him, "Tim, dear, you really need to get some exercise." And you know what he does? He just gets angry.
W: I know Mark doesn’t take exercise, either.
M: Did you tell him?
W: Of course, but you know what it is like being a mother of a 13-year-old boy. They just don’t think they need your advice anymore. I wish Mark could find a nice girlfriend to relax and have fun with. I heard Tim has a girlfriend at last. That’s wonderful.
