TESS: Have you put on weight, Ann? You look fuller in the face. ANN: I really don't care. I've given up dieting. You know, Tess. whenever I manage to lose a few pounds they just creep back on again after a few weeks, and then I feel I've tortured myself for nothing. Anyway, I'm not exactly obese, am I? TESS: No, not yet anyway. ANN: What do you mean? TESS: Well, the problem with your attitude is that, if you don't keep your weight under control, one day you might be. Surely you'd do better to diet every now and again, when you've put a few pounds on, than have to lose several stone later? ANN: But it's not like I overeat! TESS: Are you getting enough exercise, then? ANN: Actually, I don't get any. TESS: So why don't you go to the gym or something? ANN: Not my scene - all those posers in fluorescent lycra and non-stop MTV. Anyway, it's boring! TESS: Swimming? ANN: No chance! I'm blind as a bat without my glasses and the chlorine plays havoc with my highlights. TESS: Then leave your car at home and walk to work! ANN: Walk! A half-hour walk in that pollution must be the equivalent of smoking twenty a day! I'd rather be fat than have lung disease! TESS: Well, if that's the way you feel ... here - have a biscuit. ANN: Oh, thanks - can I have two?
