I definately miss high school (though not the homework or tests). Back when I was in ninth grade I realised that once you're out of school, things like weekends, summer, and holiday breaks are no longer as special (and I imagine it's the same regarding home school).
For most of my high school experience I enjoyed the attention I got from others, which hasn't been as good as after graduating. During lunch periods I'd often interract with many different groups of students, as opposed to being part of just one clique. I was pretty much a class clown throughout high school, I felt well-liked, I felt like most of my teachers were my friends, and even the people I disliked/hated/didn't get along with well were satysfiable. I do feel I should have been more popular (none of my high school yearbooks had more than one picture of me, and for some reason my student picture wasn't even in my last yearbook), and I often wish I took theater classes and whatever class it was that did the school news (the closest I took was a technology class which included some video projects, though it seemed to give more computer designing projects, and the people in my groups didn't seem to want to listen to me when I wanted to pitch my ideas for video projects).
Although I liked many of my classmates, I never hung out with any of them outside of school, and didn't have any information on contacting them (at the time there were no social networking sites I knew of). Still, after graduating high school I went to college for three years, and the interaction I got from my classmates wasn't as enjoyable (there were many times I tried talking to people who didn't seem to respond or care, even if I was trying to join in on their conversations), and my teachers felt more like bosses then friends.
Being able to get the attention of others (in person) seemed to be in it's prime during my high school years (especially twelth grade), and hasn't been the same since. I guess the only real bad thing there is that I didn't talk about Muppets to my classmates too often.
