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
Mine wasn’t really all that bad, but the time that occurs to me involves me at like 5 or 6 years old, snow, a sled, a metal fence post, and a big red bump on my forehead. I hit pretty hard, but I don’t think I was concussed or anything.
