I'm a parent, and I was what you call a "non-participant" kid who was bullied when I was in junior high and high school. Here's the thing: School ends. It's a tiny part of one's life. I know, when you're in it, it feels like it takes forever, but once you graduate high school, nobody on earth gives a shit about where you were on the social totem pole. In the grand scheme of things, the cliques and social circles are entirely unimportant, and I plan to teach my kid that. Keep your eye on the prize. K-12 school is something you simply endure until you are an adult in the adult world.
