Who is the caller?

A: Golden Hotel. May I help you?
B: Mr. John Thomas, Room 13, please.
A: Put you through. Oh, Mr. Thomas isn’t in at this moment.
B. Can I leave a message?
A: Certainly.
B: Have him call Max Green at six. It’s important.

A: Hey, John, were you in the literature class yesterday?
B: No, I couldn’t make it. Weren’t you there, either?
A: No, I wasn’t. I was hoping you could tell me the reading assignment.
