KENT: Can't you come in and have tea now, Kuan? KUAN: Not yet. I must water the garden first. KENT: Do you have to water it now? KUAN: I'm afraid I must. Look at it! It's terribly dry. KENT: What a nuisance! KUAN: Last summer it was very dry, too. Don't you remember? I had to water it every day. KENT: Well, I'll have tea by myself. KENT: That was quick! Have you finished already? KUAN: Yes. Look out of the window. KENT: It's raining! That means you don't need to water the garden. KUAN : That was a pleasant surprise. It means I can have tea, instead.
