HS was a formative experience for me. I had two dozen friends that had all grown up together so always had pals. I figured out very early that not much learning would take place in class so absorbing myself in music and sports kept me sane. The music and sports stuck with me for the rest of my life but I honestly couldn't tell you what other classes I took. I dated quite a bit but was still pretty clumsy with girls which is probably a good thing. There might be a lot more 40 yr olds around that look like me if I had developed those skills in HS.
I went to my HS 40th reunion last year and it was cool seeing faces I hadn't seen since we graduated. Everyone was very warm and friendly. I did wonder how all those former HS cheerleaders could possibly eat so much though. Whew!
Yes, college life ROCKED!
