"You can't turn into a coyote." "Can, too," I said indignantly. It was one thing for me to tell him he was lying--I knew I was right. It was an entirely different matter for him to tell me I was lying. "Can't." "Can." "Can't" "Can, too." "Mercy," Adam said with an exaggerated patience tinged with humor. He knew I was doing it on purpose. That was okay but he wasn't angry anymore. "Cannot," said Calvin. "Knock it off, both of you. Neither of you is five.””
