The unsureness of yourself at that age. How incredibly awkward and out of place you can feel, even if in reality you fit in with your own friends and in your own way.
I hated the fact that certain teachers were on a power trip. I can't stand the fact that you really didn't have rights in high school. The teacher's word was the final word, even if they were wrong. In certain classes if you disagreed with a teacher or a certain point of view and wanted to debate it you were shut down and robbed of your right to have an opinion. Yes, I know that life isn't fair and that I'll have bosses at work who will be just as unfair, but it is so refreshing to just talk or debate a point with a professor in class at college and have the chance to speak your mind.
Teachers who were on their last year before retiring and really didn't care very much about what they were teaching, the ones that had just HAD it with teaching and couldn't care less about their final year.
The pressure that was placed on all of us to be exceptionally amazing academically. That is understandable, but at my school if you werent in Honors/AP/IB classes, you weren't paid any attention to. Believe it or not, most kids were in those classes. It was the kids who scored 80s who kind of got lost in the shuffle.
I hated that we didn't have any perks senior year. That was the year that the school decided to buckle down on ALL the rules and become very strict. BTW, the next year the seniors got most of the senior perks back after they saw how badly us seniors reacted to the rules and how they really didn't make much sense.
Wow, I sound really bitter, haha. I could make a list just as long as things that I loved about high school though. For every bad teacher, there was a good one too. I don't want to make it seem like I hated my teachers, some of them touched my life, I go back and visit them when I have breaks from college. On the other hand, there were those few who made my year miserable.
