W: I’m so worried about Mare, these days. Ever since he moved into his own apartment he’s been losing weight.
M: He moved into his own apartment? Well, no wonder he’s looking so thin. He really should try to gain some weight. He’s probably not eating enough.
W: Yes. Well, anyway, bow’s Tim these days?
M: Tim? Oh, Tim has me worried, too. He is really getting much too fat. He needs to lose about 75 pounds now. I don’t know what to do. I keep telling him to go on a diet, but he gets angry every time I try to talk to him about it.
W: 75 pounds? 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. I keep telling him, "Tim, dear, you will just have to eat more fruit and less candy." He doesn’t listen to me. Maybe Marc should talk to him.
W: Well, maybe. Oh, did I tell you he’s decided to be a vegetarian? That has me very worried. He only eats vegetables and fruit.
M: Marc doesn’t eat any meat? That’s probably why he’s so thin! Does he smoke?
W: Does he smoke? About two packs of cigarettes a day. That’s my son—a smoking vegetarian.
M: Marc smokes two packs a day? Hmmm, you know, if he stopped smoking he would Rain weight. I know he would. Tim put on a lot of weight when he stopped smoking. But Tim has another problem—even worse. He drinks soda. Soda for lunch. Soda for dinner. Does Marc drink it?
W: No, not very much. Just a little from time to time. Maybe Tim needs a little exercise.
