Ignore these people, as they will just annoy you. Even Hitler had friends. At some point in your life you'll meet a girl that wants nothing to do with you other than to use you for her own gain. As long as this girl is having sex with you, you won't care. Some day you've got to hit your dad.
Hair grows back, so just go ahead.
Everyone is looking at you, constantly. Everyone who ever comes into any contact with you will judge you and judge you quickly. The trick is to remember that what they think is worthless. Kiss your bosses ass. Your pets will die.
