At seven I didn't know what sex was either. But I knew that something was wrong when a little boy in my class used every chance he got to stick his hand, hard and painfully, into my crotch. (This was back in the days when little girls wore dresses and white socks to school.) I couldn't concentrate in school because it seemed as though every time I turned my back or focused on my work he was there, crawling around on the floor under my desk and laughing maniacally. It was horrible. I was too embarrassed to tell anyone for awhile, but finally the teachers noticed. He didn't get suspended, just chewed out. That didn't do much good; he broke some of my school projects in revenge. I now realize he must have endured some kind of sexually-based torment at home to turn into such a psycho by age seven, but the fact remains that he made me miserable and that kids can sexually harass each other at a very young age.
If something like this does happen to the extent that you have described, then the parents should be held accountable. I was an ARMY brat, and if I got in trouble my dad got in trouble. If parents in society were held accountable for their kids actions, then they would be more likely to properly raise the kids.
You are so right. And Brockton is one tough place. I would NEVER send a child to a public school in Brockton.
