Thought I'd act out the part where Colin first sees Mary standing in his room in the middle of the night and cries out, 'Who are you? Are you a ghost?' Then this evening I slipped round to Georgia's house, all set to display my acting talent. I said to her, 'You've got to imagine me doing this scene in pyjamas.' 'Oh, I'd rather not,' she replied, giggling. 'This is a scene of raw power I'm about to perform for you, so show some respect,' I cried. I went out of the room and got myself all psyched up. Then I burst inside, my eyes all wide and staring and Georgia's face went so red I thought it was going to burst. 'You want to laugh, don't you?' I said. Georgia nodded and then this laugh just exploded out of her. 'I'm sorry, it's just the way you were rolling your eyes,' she said. 'It's called acting, Georgia,' I replied. 'Do it again . . . I promise I won't laugh.' 'No, I tell you what, I'll watch you instead this time.' Georgia began acting out a scene in which she's looking round the secret garden for the first time.
