Hating people because of their color is wrong. And it doesn't matter which color does the hating. It's just plain wrong.
As far as informing the headmaster, Harry had no idea where Dumbledore went during the summer holidays. He amused himself for a moment, picturing Dumbledore, with his long silver beard, full-length wizard's robes, and pointed hat, stretched out on a beach somewhere, rubbing suntan lotion onto his long crooked nose.
The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money.Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of OK for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars. Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles.But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that'd still be keeping his feet dry in ten years' time, while the poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.This was the Captain Samuel Vimes 'Boots' theory of socioeconomic unfairness.
Frigidity is desire imagined by a woman who doesn't desire the man offering himself to her. It's the desire of a woman for a man who hasn't yet come to her, whom she doesn't yet know. She's faithful to this stranger even before she belongs to him. Frigidity is the non-desire for whatever is not him.
