A: Mr. Brown, I hope I'm not disturbing you.
B: No, not at all.
A: I must make apologies. I won't be able to keep my appointment with you tomorrow morning.Unforeseen circumstances compel me to leave for New York tomorrow morning, and I'll be gone for a week. I'm afraid I've brought you too much trouble.
B: Never mind. It's understandable. Do you want to cancel the appointment?
A: No. I wonder if we could postpone the meeting to next Thursday.
B: But I've got a very tight schedule next Thursday. I might not be able to make it.
A: How about next Friday?
B: Oh, Friday is OK.
A: Will the afternoon suit you?
B: Yes, the afternoon will be just as good.
A: Then shall we make it at three o'clock?
B: Good. Three o'clock at my office.
A: OK, that's settled.
