I'll fool you with niceness , politeness, and charm. You'll see the facade of a good person--but once the curtain falls and you see the characters running around out-of-costume...you'll know that I'm a bad person, and that I'm a bad friend, and that I'm cruel.

If that happens, things will never be the same, and I'll never be good again.

(in your eyes)

Once you have the knowledge, you can't forget it.
