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
I’ve probably hurt myself worse, but one memory that stands out is me crawling around in a bush, getting my pants stuck and then losing my grip so I turn upside down with my head in a bunch of stinging nettles.
