If you wish to glimpse inside a human soul and get to know a man, don't bother analyzing his ways of being silent, of talking, of weeping, of seeing how much he is moved by noble ideas; you will get better results if you just watch him laugh. If he laughs well, he's a good man.
Man is the only animal that laughs and weeps; for he is the only animal that is struck with the difference between what things are, and what they ought to be.
I love people who make me laugh. I honestly think it's the thing I like most, to laugh. It cures a multitude of ills. It's probably the most important thing in a person.
