Mark: Hey, Joe, where are you? Remember Matt and Tracey are coming for dinner in an hour.

Joe: Hi! I've just got on the bus. I'll be home in 20 minutes. Have you made dinner yet?

Mark: What? No! I haven't started yet.

Joe: Why not? What's the problem?

Mark: We need some rice and onions.

Joe: Why didn't you tell me before? I've just been to the shop.

Mark: Well, don't worry. I can go now. I've cleaned the flat, and I've already laid the table.

Joe: OK, great. See you soon.
