Why is the woman driven crazy?

W: Excuse me. I’ve been looking at you for the last few minutes. Don’t I know you from somewhere?
M: No, no, I don’t think so.
W: Really? Are you sure? (4) This is driving me crazy because I never forget a face. Wait a minute. Did you grow up in Chicago?
M: Yes I did, as the matter of fact.
W: I think we maybe went to the same high school. Did you by any chance go to Central High?
M: Yes.
W: Do you remember me? I’m Nancy, Nancy Read. I used to sit behind you in our math class.
M: I’m Mike Green. Wow, I can’t believe you recognize me after all these years.
W: Yeah, this is really a small world.
M: I haven’t seen you since high school. How is everything going?
W: Fine. I’m a chef at a restaurant.
M: Wow, I remember you always have interests in cooking. Where are you going now?
W: I’m going to meet a friend. Oh, you maybe know her. She was in the class next door in high school, and her name is Judy Geller.
M: (5)Yes, I heard her name, but I can’t remember what she looks like.
W: (6) If you don’t mind, how about we three having dinner together this evening?
M: Ok, I’d like to meet some old friends.
