"Well, if you'd find out, I'd be game I guess. But I can't say that I wouldn't try to study, at least some. I mean, I don't want to get any detentions this year. I'm a bloody prefect you know. I'm the one they look up to, for sodding sake. I can't very well slack off."
Ron shrugged and went on, "You tell Ginny to shut it. I'd like to see how long you last after that," and Ron nudged Harry a bit with his elbow.
