Ouch! That looks like how my knee looked after I collided my bike with a minivan that pulled thru an alley out of nowhere when I was on my way to school on morning in 5th grade. I flew off my bike and slid across her hood, skidding my knee in the gravel on the way down. I probably should have gotten stitches and maybe an x-ray, but I just stayed home from school for a few days. It was the 90’s so the driver bought me a beanie baby later that day, I remember. ��

What the hell, where’s my Beanie Baby???

That is a hardcore accident for fifth grader, friend, well done.  Glad you got out of it minimally damaged!
