M: Hi, what are you doing? W: I'm cleaning the house. M: Can you go to the movies with me this afternoon? W: I don't think so. Right now I'm sweeping the floor. Then I have to wash the floors and wash and iron all the clothes. M: Aren't your sister and your mother helping you? W: No, they usually help, but today my sister is playing tennis and my mother's writing. M: That's too bad. Asian Sun is playing at the theatre. They say it's good. And I want to go to that new Chinese restaurant. W: Well, you could come over later this afternoon and watch TV with me. M: I have a good idea. Why don't I come over and help you with your work? W: Would you? M: Sure. Why not? I'll come over in half an hour.
