" Hans was never good at giving proper answers. He always had different answers in his head, odd answers, answers that his teachers and his parents and his grandmother and even his crazy grandfather seemed to think were wrong. But they weren't wrong answers, they were just his answers. He wondered suddenly what the Ice Maiden would do if he gave her a wrong answer. And, thinking this, he found he couldn't open his mouth at all. "
