Nicolas thought he could tell for a moment that he had said something wrong by asking that. He was about to ask, but decided against it. Maybe he'd ask later... but he didn't feel like he should ask right now. Besides, she had just answered him, so maybe he hadn't said something bad after all. "Cool," he said. "I've never seen it, though. I guess my favorite's The Nightmare Before Christmas."
He went silent. He was thinking of other questions to ask, plus he didn't want to say anything incase he said something bad again.
