They are typically the ones that grow up to be successful (even get married and have kids), moved on as if nothing ever happened and never once reached out to their former victims of their bullies. In fact, in you even confront them about it years later, they suddenly don't remember anything. They would even greet you as if you were some friend or acquaintance they had a good time with or greet you as if meeting you for the first time, lol.
Seriously are they actually narcissists? What do you think?
