No One Really Cares About Your Mistakes: People are too caught up in their own insecurities to notice other people's mistakes. No one is going to notice if your eyeliner isn't quite perfect or if you forgot to shave your legs. No one is going to care that you are having lunch alone or watching a movie by yourself. Remember that one time that you blurted out the wrong thing in front of a zillion people? No one there even remembered it even happened except you (when you play the scene over and over in your head, mortified, late at night when you can't sleep).
