I didn't hate high school, but I certainly didn't enjoy it. I attended two different schools - transferred after my sophomore year to another school in the same county. Both were rural schools (the one I graduated from moreso than the other), so there was plenty of "small-town politics" BS..... so if one had a certain last name you could pretty much get away with anything.
I was kind of in the middle clique, which is the worst place to be stuck.
Not popular, not unpopular, a joiner but not an over-joiner, etc. I only keep in contact with a handful of people, and most of that is sporadic. My ten year reunion is next year, don't know if I'll go or not. There's a few teachers I'd like to see more than anyone.
