When I was in my sophomore year and I had PE with my friend and we where putting some stuff away in the equipment room and then I was about to go back to the locker room but I did not see these mates between my legs so as I turned I fell back and there was a hook sticking out on the basketball rack so the hook got the surface of my arm then I didn't think of anything so I looked and there was a lot of blood coming down my side and I was laughing too so the sub teacher drove me up to the hospital and I needed 20 stitches in my left arm.
