Hey, I was never a witness but I was a geek. I was not in to drinking, partying or sex either. I was not screamingly popular. So I made friends with the library geeks. We got along OK.
I've grown up a lot, and I've found my niche. Geek kids like me grow up to run the corporation, because we do our homework. I might not be friends with the party guy down in the mail room, but there are plenty of other people out there that are great to know and hang with.
As others have said, the secret to making friends is first to know yourself and then to seek out those places where people like you hang out. There's no "worldly" and "witness". There's just people. And from recent events on the board, I'd say there's about an equal proportion of partyers, users, and abusers in both groups. And there's lots and lots of good people everywhere.
