4th of july. Me and the homies climbed onto the roof of my buddies 2 story apartment building to get a better view of the fire works. Well everything was set up, we had the lawn chairs up, the snacks and stuff, everything but the beer. I was taking a huge rip off the bong when my buddy hollered up at me to catch some beer he was tossing up. Well I had my back to the edge of the roof and didn't realize I was so close to the edge, as I turned exhaling and stepped forward there was nothing under my foot but air. I hand planted 2 storied to the ground separated my hand from my wrist and crushed my skull. Yes crushed not broken.. I stood up blood coming out of my ears and nose mad that I had broken the bong and lost my watch. I started looking for my watch. I didn't even know I was so bad off even though I saw my hand, fingers pointing at my elbow layed flat across the to of my arm..
