Naturally Shirley had known, as they slid stock words and phrases back and forth between them like beads on an abacus, that Howard must be as brimful of ecstasy as she was; but to express these feelings out loud, when the news of death was still fresh in the air, would have been tantamount to dancing naked and shrieking obscenities, and Howard and Shirley were clothed, always, in an invisible layer of decorum that they never laid aside.
J. K. RowlingI've never wanted to be a witch, but an alchemist, now that's a different matter. To invent this wizard world, I've learned a ridiculous amount about alchemy. Perhaps much of it I'll never use in the books, but I have to know in detail what magic can and cannot do in order to set the parameters and establish the stories' internal logic.
