For me, I think it was when I was playing in the yard, and saw one of my mom’s pots of dirt for her garden, and I thought “yeah this would be good to dump on my lap”
It was full of fire ants. Big, angry, north carolinian fire ants.
I was covered in red welts and all I remember is screaming at the top of my lungs while my mom sprayed me down with a hose
Aan a two year old I fell off the couch into a metal table, narrowly missing my eye, but catching my eyebrow on the corner. Still have a small scar in my eyebrow.
As a teen (13-14 ish?) I broke both bones in my forearm. That kinda sucked.
