I was never actually friends with anyone from high school because I went to a private school where everyone was really snobby. I had real good friends from my town, the best of which passed away while I was in college (not because of drinking either). I befriended people from another area school near where I waited tables, still close with them, heck, some were in my wedding party.
From college, I still keep in touch with them, but Wysky is my best friend out of there, and she was my maid of honor and we talk 2-3 times a week and try to meet up for lunch weekly.
