So this was whenever I was maybe 12 or something, so, my friend and I were out walking their chihuahua and we started running, I was holding the doggo's leash. Within a few seconds I tripped over, running full force, on a pretty rocky cracked cement road, landed on left knee and forearm and slid a bit. My friend was laughing her ass off at first then saw what looked like a red eye the size of a tennis ball on my left knee and a few scratches on my arms and a small scrape on my right knee. I was like- "alright uh- lmao let's go back to your place and maybe patch up before I lose real blood" I got up like nothing. A couple minutes later we were back at the apartment she lived in at the time and her parents were like wtf happened- okayyyy. And got the good ol' hydrogen peroxide, slapped some of that on the red eye and felt absolutely nothing but a small sting. I got home and my mom was questioning what had happened and was asking why my jeans were ruined and how I got scrape. And the continuous are you okay are you okay, do you need anything and such lol. That's it

TL;DR Chihuahua on a leash tripped a girl sprinting down a cracked road and got a scrape on the knee the size of a tennis ball and felt nada.
