Casey

“She did nothing, although sometimes when she saw him in the village she'd smile in a faint, puzzled way. After three weeks of this the suspense was too much for him and he took his own life; in fact he took it all the way across the continent, where he became a reformed character and never went home again.”
― Terry Pratchett, Wyrd Sisters

“Most people, on waking up, accelerate through a quick panicky pre-consciousness check-up: who am I, where am I, who is he/she, good god, why am I cuddling a policeman's helmet, what happened last night?
And this is because people are riddled by Doubt. It is the engine that drives them through their lives. It is the elastic band in the little model aeroplane of their soul, and they spend their time winding it up until it knots. Early morning is the worst time -there's that little moment of panic in case You have drifted away in the night and something else has moved in. This never happened to Granny Weatherwax. She went straight from asleep to instant operation on all six cylinders. She never needed to find herself because she always knew who was doing the looking.”

“I did start out in witchcraft to get boys, to tell you the truth.'
'Think I don't know that?'
'What did you start out to get, Esme?'
Granny stopped, and looked up at the frosty sky and then down at the ground.
'Dunno,' she said at last.'Even, I suppose.”

“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.”
