Man has made many machines, complex and cunning, but which of them indeed rivals the workings of his heart?
I owe much to my friends; but, all things considered, it strikes me that I owe even more to my enemies. The real person springs life under a sting even better than under a caress.
The hardest of all is learning to be a well of affection, and not a fountain; to show them we love them not when we feel like it, but when they do.
