Ron Weasley

My Gran's the same way. She won't talk about it really, but there's a man in our town who has the Dark Mark, and my Gran won't have anything to do with him, even though he's on the committee that runs the local hospital where my Gran volunteers. She's real polite to his face whenever she has to speak to him, but she crosses the street to the other side whenever she sees him coming, if she thinks she can get away with avoiding him.
