W: Love, my stomach aches．
M: Mine too, honey．
W: I think it was the fish or the meat we ate in the restaurant．
M: It might have been．
W: Or the soup．
M: No, it couldn' t have been the soup because I didn' t have any． Little Jimmy had some and he' s all right．
W: Of course we sat in the sun for a long time but I suppose it couldn' t have been the sun．

W: No, I didn' t． I thought you had．
M: Oh, Jenny, I didn't wash them, I' ve thought you did． It must have been the apples then． Oh, I feel worse now． Let' s go see a doctor．
