A: Hello, Mark Owen speaking. Can I help you?
B: Hello, Mr. Owen. This is David Smith of International Trading Co. I'm sorry you missed me when you called my office this morning. My secretary said you called concerning our meeting next Wednesday?
A: Yes, Mr. Smith, thank you for returning my call. I'm glad to finally get a hold of you. I wanted to let you know I will not be able to keep our appointment next Wednesday. I will be in Shanghai that day. Is there any possibility we can move the meeting to Tuesday?
B: I'm sorry, I'm afraid I'm completely booked on Tuesday. Would it be possible to postpone until you return?
A: Well, I was counting on taking care of our meeting before I leave, but I suppose I could shuffle a few things. Yes, I'll be back Friday morning. What about Friday afternoon? Would that will be convenient for you?
B: That should be fine. Say about 2 o'clock. OK?
A: See you.
