What do we learn about Bill?

M: Did Bill really have his two wisdom teeth pulled out?
W: Yes, his dentist suggested that he should because he had suffered a great deal of toothache since last September.
M: Oh, good. He won’t be bothered by them again.

W: We’ve been waiting all week for this concert and the performance is said to be excellent.
M: Yeah, and with our students ’discount, the tickets will be real cheap.
W: Ah, gosh ’I’m afraid I left my student ID card in the dormitory.
