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