And it hurt!
It was my fault, I put my thumb in between the door and the wall (at hinge end). Idk why I did it, it was very cold and I couldn't really feel my fingers so I guess I didn't know where they were. The door blew shut and the nail got caught. It split in half and started squirting blood, it was my first week living alone so I put a bandage on it, popper a few painkillers and tried to forget about it. The nail went into the compost bin.
