“Peace in international affairs: a period of cheating between periods of fighting”

“Peace: A period of cheating between two periods of fighting.”

“[T]he period between four and six in the morning is called the Brahmamuhurta, the Brahmic time, or divine period, and is a very sacred time to meditate. (140)”

“Life is a sandwich of activity between two periods of bed-wetting,”

“Probably some period thing. I go completely mental too. Period fever. It's the worst."This effectively killed all conversation for a while...."Fixed that," she said."You told him I had period fever," I replied. "There's no such thing as period fever.""No such thing as ghosts either.""No, there is really no such thing as period fever. There's a difference between being a guy and being an idiot.”

“Peace?' said Vetinari. 'Ah, yes, defined as period of time to allow for preparation for the next war.”
