That isn't my responsibility. Talking about the weather to them shan't improve their character, in any case
Ah. I'm sorry. Muggles are always going to war. I've a cousin who is a diplomat abroad, it can make things terribly awkward for him sometimes. I can't speak for your time, of course, but the mudbloods of my era would likely have a far harder time to integrate if there were lessons discussing the habits and beliefs of muggles. It'd be unkind to those who want to get on. There's a mudblood chap in my form, Cotterell, he's poor but awfully clever in a Ravenclaw sort of way and he wants to fit in, so I don't hold with anyone making his life more difficult.
