i'm not in touch with my HS or college friends. SOME of them, but i wouldn't say i'm close with them anymore.
i got to say though, COLLEGE was a great experience for me. my parents were much more lenient and i was having more fun with more "mature" friends doing what i thought back then was "mature" fun... like partying and getting shiitfaced drunk and running off to beaches for more parties.
college problems were much heavier too -- sex, drug use and addiction, suicides, running away from home to run off with boyfriends/girlfriends, etc... you name it, i've had a friend run to me with that problem. those made us all closer during those times.
that being said, i'd still say college was an awesome, awesome time, and i'd love to re-live those again... if i were still even close to my college barkada.
after college though, i went to another school -- film school, where everyone i knew were almost exactly like me, and i found genuine relationships there, including my boyfriend. life after college, i got to say is way, way more fun.
