[speaker001:] Can 't you come in and have tea now, Peter?
[speaker002:] Not yet, I must water the garden first.
[speaker001:] Do you have to water it now?
[speaker002:] I 'm afraid I must. Look at it! It 's terribly dry.
[speaker001:] What a nuisance!
[speaker002:] Last summer it was very dry, too. Don 't you remember? I had to water it every day.
[speaker001:] Well, I 'll have tea by myself. That was quick! Have you finished already?
[speaker002:] Yes, Look out of the window.
[speaker001:] It 's raining. That means you needn 't water the garden.
[speaker002:] That was a pleasant surprise. It means I can have tea, instead.
