Light: May I call at your office sometime1?

John: Certainly. You're always welcome. When would you like to come?

Light: Well, when will it be convenient2 for you?

John: Let me see, I'm usually busy in the morning. So you might come over some afternoon, say, between four and five, if that suits you.

Light: How about next Monday afternoon?

John: Yes, that's fine. I'll tell my secretary to fix us a working dinner.

Light: That's very kind of you. See you then.
