Light: I'm afraid I won't be able to keep my appointment with you next Thursday, after all. You see, I've got to go to New York on urgent business. I'm very sorry about it.
Zhang: Well, I understand, but how long will you be gone?
Light: Only a week or so. I'll be back before the weekend after next. So I'm calling to see if we could change the time for our meeting to Friday after next.
Zhang: Certainly. What about the morning?
Light: No, please come over at three, and after that I'll take you to a restaurant I know.
Zhang: That'd be very kind of you.
Light: See you then! I'm sorry about the postponement.
Zhang: That's alright. Have a nice trip! Good-bye!
