Mr.Zhang: Hi, Andy. Hi, Mary. Where are you going to do tonight?
Andy: I'm going to go to the swimming pool.
Mr.Zhang: Oh, be careful. You mustn't walk quickly near the swimming pool.
Andy: I know. I must walk slowly.
Mr.Zhang: Where are you going to go, Mary?
Mary: First, I'm going to go to the cinema.
Mr.Zhang: You mustn't talk loudly there.
Mary: Yes, I'll listen carefully and put my rubbish in the bin.
Mr.Zhang: Where are you going to go next?
Mary: Then I'm going to go to the hospital to visit my grandma.
Mr.Zhang: Well, you must talk quietly and you mustn't run in the corridor.
Mary: That's right, Mr.Zhang. Have a good evening.
Mr.Zhang: You too.
