What’s a secret you found out that you were 100% not supposed to know?

When was just becoming an adolescent my mom dragged me off to church for one of the very last times I'd put up with it before I shared that story of literally jumping out of the Van to avoid being dragged back to another meeting with the witnesses and scraping my knee but One of the last times I went I ran into a Sister Garcia and remembered this bully of a classmate I Had that non-stop trash talked the witnesses and noticed they had the same last name and asked Sister Garcia if they were related and of course, Naive to the Drama between us, she told me. confirming the suspicon about Cara Garcia (Not the other Cara that died on me that I sometimes talk about, The bully is just someone else who unfortunatey had the same name)

She swore me to secrecy but I found out later on that she unleashed hell on one of my best friends, a girl in the locker rooms, potentially crossing the line into sexual harassment, molestation, etc. All in a gambit to get at me through my friends.

Completely deranged. Had obsessive enemies as a kid. Fortunately, I got out of town and forgotten about. I never told a soul, but she was still pissed I found out.
