Utterly Mad

I had a similar story when a friend stabbed me in the arm, made a makeshift bandage and tourniquet and carried on, eventually my dad found out and I went to the hospital to have it stitched up, wound was about an inch wide, two inches long.
Turns out the wound was deep enough to cause serious nerve and tendon damage and I've never been able to move my fingers properly since, although I've been slowly getting my fine motor skills back with my hand lately.

Dad was gonna shoot me in the leg with a blunt crossbow bolt once, through a thick leather trenchcoat I had, I was obviously completely up for it, but decided to shoot it at the door first to see what kind of damage it might do. It went right through the door and nearly stuck into the wall behind it, we decided it was a bad idea to shoot me with it after that.

My sense of self-preservation used to be pretty awful apparently.
