[Q]: W: Late last night? That's strange. What did he look like? M: He seemed to be about thirty or so. W: Was he tall or short? M: He wasn't very tall, nor very short. About aver age height, I think. W: Was he fat or thin? M: A bit thin, if I remember correctly. Anyway, certainly not fat, but then he wasn't very thin either. W: Was there anything unusual about his looks? What kind of face did he have-round, square or long? M: Let me think...It was rather square, but not very. Or was it? Really, I didn't notice. It was so late and the lighting wasn't good. W: Was he wearing glasses? M: Was he or wasn't he? I'm not sure now. You see, I was so tired and sleepy. I didn't notice. I didn't pay much attention. What was said before this conversation?

[A]: M: Tom must be joking when he said he plans to sell his shop and go to medical school.
