I have a scar on the back of my right leg from going down a slide when I was in 3rd grade. I don't know how it happened. All I know is that I went to go on the slide and when I stepped off there was blood on my leg that a teacher had seen (I didn't even notice. There was no pain). I think it was because it was hot out that day and the sun was blazing. That slide was hot pretty hot though.
