It may not be the popular opinion, but I loved my high school.
It was a large building which meant I had to walk quite a ways between my classes in the limited amount of time permitted between periods, but that was fine.
The classrooms themselves were very roomy so the desks weren’t crowding each other. All of the teachers I had throughout my years there were pretty nice and gave a reasonable amount of work. I really enjoyed my extra-curricular activities, art and chorus, and attending the school performances for the band and drama club was always fun. The lunches definitely left something to be desired, but they weren’t inedible. All of that aside, there was one thing about my school I absolutely hated, and that was the temperature within the classrooms. One of my teachers explained to me that the school’s entire HVAC system was controlled off-site, so no one in the school could actually adjust the heating or cooling within the classrooms. Often times the air conditioner was left running well into the colder part of autumn, and us students would need to wear jackets in the classroom. For a short period of time in winter the furnace would be running, heating up the classrooms, but once the weather started to warm up outside it was turned off, despite it still being chilly. And then, near the end of the school year as summer approached, the air conditioner was left off despite the rising heat, leaving whatever breeze could be gained through open windows or electric fans as our only relief. The school would have been nearly perfect if only it had had HVAC zone control on-site so that the teachers could all adjust the temperature in their classrooms as needed.
