"Finger Scar and Falling Stone"

I have this scar on the ring finger of my left hand. Its one of those scars that indents. It wasn't until a couple years ago I remembered how I got it. In preschool we liked to play this game where we would pick up a giant rock and throw it at a another giant rock that protruded from the ground. What we would do, then, is we would stick our hand on the bottom rock and someone would toss the other rock down and we would see if we could get our hand out of the way. Well... one day I didn't.
