“Yeah, Quirrell was a great teacher. There was just that minor drawback of him having Lord Voldemort sticking out of the back of his head!”

“Well, I had one that I was playing Quidditch the other night”, said Ron, screwing up his face in an effort to remember, “What do you think that means?”

“Wow, I wonder what it’d be like to have a difficult life?”, said Harry sarcastically.

“Cool name”, said Harry, grinning, “But you’ll always be Ickle Diddykins to me.”

“Listening to the news! Again?”

“You know your mother, Malfoy? The expression on her face - like she’s got dung under her nose? Is she like that all the time or just because you were with her?”
