People who sound insincere all the time […] should not expect others to notice the difference when they try to sound insincere. - Kingsley Amis

'What's that stuff they put in ships to keep them from going all over the place?'
'What? Oh … ballast?'
'That's right. People's sex drives are like ballast, they keep them steady. It sounds wrong, but they do.'

A great British prime minister once remarked that the people were divided into two nations, the rich and the poor, and in effect that these had no knowledge of each other. One might say the same, perhaps, of those who live in parts of the world where segregation by races is practised. But these barriers, or the reasons for them, belong to a part of our history which is fortunately passing away. There is one barrier, however, which no amount of progress or tolerance or legislation can ever diminish. I'm talking about the barrier between the attractive and the unattractive.

Friendship includes charity. But there's no charity in sex.
