Getting Rid of a Man's Left Hand

Andy was in the process of getting rid of all his unneeded possessions when he started doing this weird thing with his left hand. He had somehow managed to get his hand on a large ten inch long piece of metal then sharpened off one end into a point. To this day, I don't think Andy would have actually hurt me or anyone else for that matter. It's just so crazy to me that a head injury can have such a bizarre and terrifying effect on someone's thought processes. Like Andy isn't even really Andy anymore, not since the accident. He's Andy in name only.
