" When they reached the house, Wally took a box of crackers up to his room and sat on the floor to eat them, his back against his bed. He still couldn’t believe that he was the one who had officially declared war on the Malloys. How had it happened? Only a week before he was lying on his back in the grass, and now here he was: Number One on their Most-Wanted list. He was on bad terms already with his teacher, had almost broken Caroline’s nose, and had made everything worse by calling her sisters stupid.
Well, they were stupid. And deep down, seven layers beneath his skin, Wally knew he was glad that he had thrust his head back and bumped Caroline. He’d just wanted her to stop bugging him, that’s all. But her nose sure looked peculiar by the end of the day—a lot redder and fatter than it had looked that morning.
Then he had another thought: What if it really was broken, she had to have an operation, and he had to pay for it? His hands began to sweat, and he swallowed the piece of cracker in his mouth without chewing. Was there such a thing as just a sprained nose? A bruised nose? A slightly but not completely fractured nose? A bent nose, maybe? "
