I don't know if this counts, it sounds obvious now as an adult but as a kid, you just don't know better.

When I was young, around 14, my sister and her husband, both in their late twenties, lived with my family in Texas. My sister's husband was a weird guy, we got along but he was always just strange in his behavior.

At night when I would wake up to use the bathroom, he would be in there for hours with his computer and headphones so I'd have to wait about two hours for him to leave. He would do that every night. Things got bad when I would find him in my bedroom when I got back from school, on my desk or bed, and he would say something stupid like he needed a quiet place. Then he would randomly open the door in the mornings to wake me up for when I had to go to school, once I even woke up to him rubbing my foot over the covers, that's when I would scream at him to leave.

I never went to my parents cause I was always thinking that he was just being really weird but would stop when he knew it made me mad or unfomftable. Something felt super off though, and alarm bells went off when my sister said she was pregnant. It just fel like this was now too permanent, like she (or we) would never be rid of him.

A couple years later he went to prison for molesting my baby neice. I'm so terriby hurt that this happened to her, and I'm frightened about what will happen when he eventually gets out.
