I was also one of those nerdy ones. I was in high school before all those school shooting stories got everybody panicking though. So being the quiet kid in the corner didn't do much there. That and I was a skinny runt until about 10th grade. I got in fights every so often but rarely more than little scuffles, and I ended up on the losing end more often or not.
I moved to a new school in 3rd grade, and would remain in that school district until 11th grade. I was the class clown that nobody liked from about 3-6th grade. I was a plain wannabe loser who hung out with people who took advantage of my desperation from about 7-8th grade. Through all these 5 years, I was picked on a fair amount, and attacked a few times.
In 8th grade my family got internet. I started being social online, and wasn't so desperate to be social in "real life". I started learning about the world and realizing the place I lived was extremely backwards, and that it was foolish for me to try and fit in with them. I became the archetypal 'quiet one'.
I didn't know many people outside of my grade until 10th grade, when classes started mixing together more. I met a small group of outcasts all a grade or two higher than me. These people were referred to as "the black trenchcoat gang" BEFORE Columbine happened. Then that spring... Columbine happened. Around this same time, I'd been told that we were moving soon, and I started getting a lot more outspoken. Interesting times. You couldn't have been caught more in the middle of that cultural backlash than I was. People were scared of me, and not in the left-me-alone kind of way. It's a good thing there wasn't much school year left at that point, and we moved away. Things probably would have gotten really ugly.
