Never had a problem with High School. I grew up in a small town so there weren't many cliques (except for maybe the 'douchebag stoners' and then 'everyone else, including the stoners that weren't doucehbags') and most people knew each other. I never really got picked on much and everyone liked me or didn't hate me enough to go out of their way to show it.
Honestly, Junior High and Grade School was worse. Kids were such shitheads at those ages and with High School, I at least had SOME say in what classes I wanted to take whereas with Grade School it was all 'Okay, math is over, take out your blunted scissors and 4-inch thick construction paper and... JIMMY, STOP EATING GLUE!' Fuck that. I don't miss much from those days.
Not that I'm really all that nostalgic about HS. It was just a part of my life. For every teacher that put me to sleep during class, there was always another that managed to make even the dreariest of subjects bearable . I suck ass at math (I barely passed Algebra and that was with spending a lot of time after school working on it... with my Algebra teacher who kinda sucked), but my Geometry teacher was great. He knew how to teach and get the information across without just blindly lecturing.
I took a 'study period' in which I was supposed to be working on my computer programming, but I spent most of the time online and playing MUDS with my friends.
My World Geography teacher was great. Every year, he'd let the students pick which countries we wanted to study and then he'd talk about those. He also told stories of his debauched college lifestyle, which were also informative and entertaining.
I do really miss college though. If I could figure out how to Van Wilder my way through life, I'd totally do it. Fuck working. Jobs suck.
