What's something you did as a child, later to realize was really unacceptable / inappropriate?

This was when I was in the 3rd grade. The bell rang, and I was walking out of the school playground to walk home with some friends where a lot of parents went to go pick up their kids. When out of nowhere a parent ran up to me, grabbed my arm, then violently shook me yelling at me to stop bullying her son. I knew the kid that she was talking about, but had no idea what event she was referring to. I had never bullied her kid, or even made fun of him, but apparently he's been telling his mom that I've been bullying him for some time now. She was shaking me for about a good 10-seconds, and even slapped me. I was crying my ass off full of confused emotions trying to make sense of it all. I couldn't even remember what else she was screaming at me for, and I was kind of surprised none of the parents or supervisors stepped in.

A few of my friends ran up to her telling her that I had done no such thing, but she didn't seem to care. I walked home trying to process what had just happened, and by the time I got home I was back to being normal. But 30-minutes later, I hear the phone go off and my mom goes to answer it. After a few minutes, my mom puts the phone down and tells me to come over and tells me that someone wants to talk to me. It's the same woman who grabbed me earlier that day. She was now calling me to demand that I apologize to her and her son for causing them problems. I was just a kid and didn't know how to process these things, so I just apologized over the phone, then hung up. Looking back all these years I realize I should've explained it more in detail to my parents about what had happened, and that woman probably should have been reported for some kind of child abuse.

Maybe a year later, the same kid who claimed I was bullying him kicked me in the face while I was playing an instrument during band practice. There was blood everywhere and I had to go to the nurses office. I reported him, but apparently he made up some lie about me again to get out of it, and the assistant principal had to get involved thinking there was some beef between the two of us. I wish I had the capacity back then to speak up about what had actually happened to the adults back then. That kid had some serious f*king issues.
