B: I'm sorry to hear that. I do wish you'd think it over, though.

A: Quitting? But why?

B: I like my job, but I haven't had a promotion since I started. I don't think there is any future for me.

A: Was your proposal accepted?

B: No, it was turned down.

A: Do you think you could look over these documents today?

B: I'm sorry, but I have a pile of work to do.

A: Won't you have some more?

B: No, thank you.

A: Mr. Mills wants to speak to you.

B:  I'm very busy right now. Ask him to call me back later.

A: Suppose we wait till tomorrow.

B: I'd rather not.

A: I'm sorry, but I won't be able to see you this evening.

B: You don't mean it, do you?
