I don't like nastiness at all, but it does have the peculiar effect of making some men seem more dashing. Just some men, mind. It certainly doesn't do anything for Ron Weasley! Or Zacharias Smith.

This isn't about you fancying Ginny Weasley, is it? Because I doubt you'd have to work terribly hard to get a girl's attention, especially one younger and in a house like Gryffindor. You're the only Malfoy in the school, last I checked.
