I have to agree with you.  I was never 'popular' in high school (to me, that meant being flocked with 'friends' everywhere you went).  I was too shy.  (HA!  no longer!)

But I wan't unpopular, either, so to speak.  At least, not in senior high.  I didn't really have any enemies, per se, but I wasn't in any large cliques.  I think I didn't get picked on mostly because I was nice to people...

And now, I don't really care so much what other people think about how I look, or what I wear, or anything...  And I'm not so afraid to speak out, either. Hm...  I think it might be plain old maturity in my case.  ;)
