I know whether of not your statement is true, and you know that I know whether or not it is true, because it is about me. But do you know that your statement is true? This is what I mean by passing judgment.

When one says, I won't judge you for that, what they're really saying is, I am judging you for that. Think about it. If you walk into my house and I tell you, "I won't judge you for wearing those pants," what am I really saying?
