whoa DDay, Sorry to hear that... sounds awful.

Not so light-hearted there. :/
But yeah, worst school memories? Far to many.
-Getting my head slammed into the ground by a crazy shithead in elementary school... It actually happened a few times. kid was a wrestling buff, ended up getting into 'gangsta' criminal shit later in life.
-Being called Wilbur in gym class. Q-Tip on my bus later (I got caught picking at my ear once).
-Being constantly harassed on my high school bus (by kids younger than me -_-)
-Someone running into me in the hall causing me to spin due to the angle, dropping all my papers and books. Literally, having nearby kids laughing and pointing.
Shit man, just scratches the surface... no nerd retribution or karmic re-balance here either, life got better in college (surrounded by other gaming nerds, I became far more social), then worse, as I still can't get a fucking job, and I'm living with my parents in a Indiana redneck-hell of a town.
These are probably not the responses you bargained for. :P
