What do we learn from the conversation?

W: How nice day, isn’t it? Brian, let’s go swimming.
M: OK, Cindy ,if you don’t mind waiting. Before I go with you, I must finish my term paper. You know, it’s due to 3 o’clock.

W: I’ve got to meet Daniel Black at the station, but I don’t know what he looks like. Do you know him?
M: Well, I met him once last year. He’s quite nice-looking really. He’s got dark hair. Rather long. No mustache or beard.
W: Does he wear glasses?
M: Er...let me think. I really can’t remember.
