I have a scar right below my knee on my left leg. Me and a bunch of people were playing football at some local elementary school's field. It was really muddy and wet and I was probably the only person not wearing cleats. Anyway, I tackle my friend and he steps on my leg with his cleats. I really didn't feel it at the time, but then I felt something wet on the inside of my pant leg. I folded it up and there was a large amount of blood just rushing down my leg. So.. went home and cleaned it up. It didn't require stitches or anything (although my mom was freaking out saying it would), and it finally healed on its own.
