Yeah, I have memories of things that I had done that in hindsight were hurtful to another. I don't think I was mean to anyone on purpose....but the idea of not fitting in with friends and going with the crowd sure is a hard thing for a child to turn away from.
I hope you are able to forgive yourself for anything you had done as a child who didn't know better. We had a lot to learn as children don't you think?
