Dialogue:

W: Your father and Sally have gone to get the car. Let's wait for them here on the bench.

M: It's nice to sit down. We've been walking for hours.

W: Did you like the White House?

M: Oh, yes. I thought it was beautiful. I wanted to stay longer.

W: I did, too. But we've got a lot of things to see.

M: The line wasn't long this morning, was it?

W: No, it wasn't. We were lucky.

M: I wonder if the president and his family use the rooms we saw. They look more like a museum than somebody's house.

W: Yes. They are the public rooms. The President's family lives upstairs.

M: What do they use the public rooms for?

W: For important affairs. The President usually entertains members of the government and visitors from other countries.

M: I hope I could get a reception at the White House some time.

W: Well, if you do something important when you grow up, maybe you will. Who knows?
