For anyone out there, I have to write a short story of a scar, can anyone help?

One time, I was riding an ATV with my friends at a secluded park and we were having lots of fun. My friend came up with the idea to ride the ATV together, one facing forward and one facing backwards. I was a bit hesitant at first, but then decided to do it because I didn't want to look like a wimp. When we initially started, it was pretty fun, but it started getting more and more dangerous once he started going faster. before the accident occured, I must have almost fallen off 5-9 times. What happend was there was there was a tiny hill not enough to throw anyone if it was only one person riding the ATV, but because there was two, it got pretty bad. I was thrown off, going 50 mph in a residential area and my friend served and hit a truck. we immediately got out of there and never spoke about i again. AN that is how I got my scar both of my arms.
