Tea for Two

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