I somehow know through, I don't know, invisible tentacle whiskers or something, that Peter's mother's side of the family are posher than mine (no money at all, but lots of inherited furniture and books, mostly from a large number of ancestors who were vicars) and his father's side are more or less bobbing around at the same level with my lot, with differences mostly down to one family being Northern and musical, and the other Southern and not.

I am at the same time fascinated by this and enraged by it.
