“His sister had been sent down to the village to ask Mistress Garlick the witch how you stopped spelling recommendation.”

“Nanny Ogg knew how to start spelling 'banana', but didn't know how you stopped.”

“This time it had been magic. And it didn't stop being magic just because you found out how it was done.”

“And what do you really do?" asked Tiffany. The thin witch hesitated for a moment, and then: "We look to ... the edges," said Mistress Weatherwax. "There's a lot of edges, more than people know. Between life and death, this world and the next, night and day, right and wrong ... an' they need watchin'. We watch 'em, we guard the sum of things. And we never ask for any reward. That's important.”

“When it came down to it and the life-or-death decision had to be made, then it was made by you, because you were the witch. And sometimes it wasn't a decision between a good thing or a bad thing, but a decision between to bad things: no right choices, just... choices.”

“There was a wicked ole witch once called Black Aliss. She was an unholy terror. There's never been one worse or more powerful. Until now. Because I could spit in her eye and steal her teeth, see. Because she didn't know Right from Wrong, so she got all twisted up, and that was the end of her."The trouble is, you see, that if you do know Right from Wrong, you can't choose Wrong. You just can't do it and live. So.. if I was a bad witch I could make Mister Salzella's muscles turn against his bones and break them where he stood... if I was bad. I could do things inside his head, change the shape he thinks he is, and he'd be down on what had been his knees and begging to be turned into a frog... if I was bad. I could leave him with a mind like a scrambled egg, listening to colors and hearing smells...if I was bad. Oh yes." There was another sigh, deeper and more heartfelt."But I can't do none of that stuff. That wouldn't be Right."She gave a deprecating little chuckle. And if Nanny Ogg had been listening, she would have resolved as follows: that no maddened cackle from Black Aliss of infamous memory, no evil little giggle from some crazed Vampyre whose morals were worse than his spelling, no side-splitting guffaw from the most inventive torturer, was quite so unnerving as a happy little chuckle from a Granny Weatherwax about to do what's best.”

“I'm not the world's greatest expert, but I would have thought that the wizards, witches, trolls, unicorns, ... broomsticks and spells would have given her a clue?' - when J.K. Rowling insisted she wasn't writing fantasy.”
