Oh, monsters are scared', said Lettie. 'And as for grown-ups...' She stopped talking, rubbed her freckled nose with a finger. Then, 'I'm going to tell you something important. Grown-ups don't look like grown-ups on the inside either. Outside, they're big and thoughtless and they always know what they're doing. Inside, they look just like they always have. Like they did when they were your age. The truth is, there aren't any grown-ups. Not one, in the whole wide world.' ... We sat there, side by side, on the old wooden bench, not saying anything. I thought about adults. I wondered if that was true: if they were all really children wrapped in adult bodies, like children's books hidden in the middle of dull, long books. The kind with no pictures or conversations.
