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
My parents had a caravan when I was like 4 years old. Ran into it full speed, hit my head hard. I had an anger attack because blood was coming out of my head, my parents got a heart attack because of all the blood.
Another one would be when I found out I needed glasses. At school, at the gym class, we were playing around as a warming up.
I ran after a ball, and hit one of those horizontal bars you can do tricks on. Full speed, nose first. That hurt for a couple of days. Spent the rest of the class holding my nose closed because I was bleeding a lot.
