"Nobody looks like what they really are on the inside. You don't. I don't. People are much more complicated than that. It's true of everybody.' I said, 'Are you a monster? Like Ursula Monkton?' Lettie threw a pebble into the pond. 'I don't think so,' she said. 'Monsters come in all shapes and sizes, Some of them are things people are scared of. Some of them are things that look like things people used to be scared of a long time ago. Sometimes monsters are things people should be scared of, but they aren't.' I said, 'People should be scared of Ursula Monkton.' 'P'raps. What do you think Ursula Monkton is scared of?' 'Dunno. Why do you think she's scared of anything? She's a grown-up, isn't she? Grown-ups and monsters aren't scared of things.' Oh, monsters are scared," said Lettie. "That's why they're monsters. 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. Truth is, there aren't any grown-ups. Not one, in the whole wide world."
