Oh dear , my weight has gone up again .   I am not surprised , you eat too much .   And I suppose sitting at the desk all day in the office doesn't help .   No , I wouldn't think so .   I do wish I could lose weight .   Well , why don't you go on the diet ?   I've tried diets before but they've never worked .   Perhaps you should excercise more . Why don't you go to an exercise class .   Yes , maybe I should .
