At ten my older sister had the house key.
She was 12.
We got separated when I broke my collar bone playing football. Full tackle no pads. She kept playing.
I broke into the house (no damage) through a basement window, crawled through and fell into a couch.
Called my Dad who was really pissed off that he had to come home from work to take me to the hospital.
He did ask how I got into the house.
“That’s my Boy!!”
Here’s a key.
Nothing so traumatic for me but my parents left me with my brothers one night and they took off to hang out with their friends so I was home alone until way after midnight...I never told.
