I still remember my first fight, it was at school in 2d grade in Seattle. I was a new kid, a jerk jumped me right in class for touching his chair. Luckily it was harmless. I was not bullied after probably because I was not small or completely friendless even though I was shy and quiet.
The next time was in 5th grade in Texas (new kid again -- I was the weirdo from Seattle). Also harmless. We didn't even get suspended or put on detention in those days.
The next time was in the Army defending someone who was being bullied by a racist. That was scary for me because I was so angry I could have really hurt someone. Luckily, cooler heads intervened.
Growing up, I heard stories from cousins that went to public school in the Chicago area. Major fights everyday. Though they managed to stay out of harms way.
Back in Seattle, my son got suspended for play fighting in middle school (zero tolerance) but otherwise he made it out without getting into any fights -- it helped that he was/is very tall and a popular athlete.
Onetime when I picked him up after a dance there was a horrible fight where a large girl was beating the shit out of a smaller girl with 100s of kids whooping it up around them. Crazy time.
Plenty of more stories from his time in bad schools in South Seattle. Scenes out of a movie bad. Most people can't imagine the out-control violent environment that exists in some US public schools. Even in cities like Seattle.
I can't imagine how bad it could be for kids forced to go to bad schools in big cities like Baltimore, Philly, Chicago, LA, DC, and such.
