“There are, it has been said, two types of people in the world. There are those who, when presented with a glass that is exactly half full, say: this glass is half full. And then there are those who say: this glass is half empty.
The world belongs, however, to those who can look at the glass and say: What's up with this glass? Excuse me? Excuse me? This is my glass? I don't think so. My glass was full! And it was a bigger glass! Who's been pinching my beer?
And at the other end of the bar the world is full of the other type of person, who has a broken glass, or a glass that has been carelessly knocked over (usually by one of the people calling for a larger glass) or who had no glass at all, because he was at the back of the crowd and had failed to catch the barman's eye. ”

“Tiffany knew what the problem was immediately. She'd seen it before, at
birthday parties. Her brother was suffering from tragic sweet
deprivation. Yes, he was surrounded by sweets. But the moment he took any
sweet at all, said his sugar-addled brain, that meant he was not taking
all the rest. And there were so many sweets he'd never be able to eat
them all. It was too much to cope with. The only solution was to burst
into tears.”

“That bit where that lad sprang backwards right across the room with them axes in his hands was impressive, though."

"Yeah."

"You didn't ought to have stuck your sword out like that, I thought."

"He's learned an important lesson."

"It won't do him much good now where he's gone.”

“Your average witch is not, by nature, a social animal as far as other witches are concerned. There's a conflict of dominant personalities. There's a group of ringleaders without a ring. There's the basic unwritten rule of witchcraft, which is 'Don't do what you will, do what I say.' The natural size of a coven is one. Witches only get together when they can't avoid it.”
