The thing that was the worse would be all the rules and regulations. I think at that age you need rules, but the high school I went to just got ridiculously strict. It got to where I felt I was being turned into a robot and programmed to fit the facultys wants. The dress code did not allow you to express yourself. Some rules are okay to keep students in line, but when it is to the point where you can't play around with a friend in fear of being sent to the office for assult, it has gone too far.
School is no longer an enjoyable experience.
