I was kicked out on day 5 for a semester for communication of a threatening nature. I was mostly a loner and drifted between groups of friends. Sometimes people were followers of mine for one reason or another. I was assertive, calm, had more depth and rationality than my peers, and expected everyone else to be on my level of intelligence and control. So I was disappointed repeatedly and often with my peers.
Sophomore year an entire half of the school showed up to see me get attacked by twenty-odd seniors, but I kept them in conversation long enough that the authorities at the school showed up. Then I had a planned fight with an ex-friend of mine. I started off winning the fight handily, but I genuinely didn't want to hurt him, and he just kept getting back up angrier and angrier. When I finally turned my back on him and told him it was over, he tackled me from behind and started bashing my head into the street.
Most of my other very specific memories were about girls I liked and how I rejected them or ran away from them despite wanting to not do that on some level. Also having a job for a little bit.
Oh, and a lot of Dungeons and Dragons.
