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
Funnily enough, mine’s also garden-pot related. I was playing with my sister and our friend and I tripped over and faceplanted into a terracotta pot. It could’ve been a lot worse because there was a cactus in it, but even as it was I needed six stitches.
