A： Hello，Mike，this is Wang Tao.

B： Hi，Wang Tao. How've you been？

A： Just fine. I am having some people over Saturday night-sort of a housewarming party for the new place. I was wondering if you would like to come.

B： Oh，that sounds great. What time？

A： Um，eightish .

B： Oh，I'm afraid I won't be able to make it. I'm going out of town for the weekend.

A： That's too bad. I want to show you what I've done with the place. You haven't seen it since before the renovations started.

B： I guess I'll have to take a raincheck on that. Can I get the grand tour some other time？

A： Sure. why don't you drop by sometime？

B： I'll give you a call when I come back. Maybe we can set something up.

A： Oh，and Mike——you do have my address，don't you？

B： No， come to think of it， I don't. Hang on while I get a pen.
