During my time in the camps, I had got to know the enemies of the human race quite well: they respect the big fist and nothing else; the harder you slug them, the safer you will be.
Aleksandr SolzhenitsynLike a bicycle, like a wheel that, once rolling, is stable only so long as it keeps moving but falls when its momentum stops, so the game between a man and woman, once begun, can exist only so long as it progresses. If the forward movement today is no more than it was yesterday, the game is over.
