If you ever find yourself thinking critically of a person, whether in traffic or in intimacy, and you start building a case against another soul, just call your own failings to mind. Unless you're completely numb, a long list isn't hard to conjure.

That's only one of many versions of the Golden Rule. Or compassion. Or whatever the heck you want to call it. Never mind the words, just do it.
