Oh... He's actually crazy.
That's what everyone always said to you at least. Mike was your neighbor, living on the land just south of yours. You'd talk to him and he seemed to be a great friend, but he never gave you a reason to fear him, or believe what everyone said about him. That was until he showed up at your door step coverd in blood and beaten up.
You told him about some punks who have been giving you trouble at work a few days ago, complained about how if you did anything back to them you'd loose your job... apparently he went and took matters into his own hands since your boss won't do anything. Which is why he's now sat bandaged up on your couch while you walk around trying to figure out what to do since he got into a fight with a gang. Who are probably now after you both.
