Of all the nonsense that twists the world, the concept of 'altruism' is the worst. People do what they want to, every time. If it pains them to make a choice - if the choice looks like a 'sacrifice' - you can be sure that it is no nobler than the discomfort caused by greediness... the necessity of deciding between two things you want when you can't have both.
Robert A. HeinleinSome logics get nervous breakdowns. Overloaded phone system behaves like frightened child. Mike did not have upsets, acquired sense of humor instead. Low one. If he were a man, you wouldn't dare stoop over. His idea of thigh-slapper would be to dump you out of bed — or put itch powder in pressure suit.
