Psycho in my Head

Fred was the voice living in my head. He must have wanted me dead. He would yell and scream until he got his way, I did everything he said without pay. I parachuted out of a plane and challenged people to fights, all in the middle of many a great nights. I got mad one day and hit his face, hurting mine as well. Living with Fred could be a living hell. I told him to go away and he refused. He said no, sounding amused. It looks like Fred and I have to get along. I hate being used.
