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
Made an awkward turn while playing and had a knee subluxation. Brief agony until I “popped” it back in and insisted I was fine. Limped around for the rest of the day, hurt for the rest of the week. For several years after, it would randomly happen again, though less severe, quicker to recover, and less frequent between incidents. Didn’t bother to get it checked out since I heard any significant knee surgery would take me out of commission for some months. I’m still not sure if I’m completely over it yet. God forbid it happens to me on the stairs
