I headbutted a wall . . . the wall won.

I'm not the most coordinated guy on the block, and 2nd grade was no exception. My brother, cousin, and I were playing in the hallway at my house. I must have tripped and fallen into the corner of the wall. I hit my head pretty hard and knew I was hurt. I just didn't know how badly I was hurt until my parents saw the blood. They immediately rushed me to a walk-in clinic down the road and I ended up with 13 stitches. The cut was deep enough that the doctor could see my skull. Pretty nasty, but luckily no skull damage.
