Draco Malfoy: This is Crabbe, and Goyle. And I'm Malfoy. Draco Malfoy. (Ron snickers) Think my name's funny, do you? I've no need to ask yours. Red hair and a hand-me-down robe? You must be a Weasley. We'll soon find out that some wizarding families are better than others, Potter. You don't want to go making friends with the wrong sort. I can help you there. (Draco extends a hand towards Harry, Harry doesn't shake it)

Harry Potter: I think I can tell the wrong sort for myself, thanks.
