Snapedom

You know, I was going to comment that I didn't see Lily as going to a private school, but the idea is definitely growing on me. I don't see the Evans' as rich, precisely (although as you say, definitely better off than the Snapes who lived on the dodgy council estate in the arse-end of their town) - maybe they scrimped and saved to meet the school fees, wanting their kids to get a good education, and in Petunia this translated into an obsession with keeping up appearances, as she was uncomfortably aware of not being so well off as some of her classmates.

But yes, I don't think they could have gone to the same school. If you believe JKR, Eileen would have been brought up in a tradition of homeschooling - but maybeTobias would have insisted on his son going to a proper school, where he was bullied and ostracised for being such a weirdo with funny clothes. I don't expect the teachers liked him either, as he would have been scornful of science lessons and other Muggle stuff, and was probably years ahead of the other kids by virtue of his own reading (although in rather different subjects than they taught).

Oh, and he was always crap at games, mostly because he didn't want to be there.
