aww Don't feel dumb! I have some really good friends that know practically nothing about JRock and we find other things to babble about. Plus, sometimes we do talk JRock just 'cause they like to learn. hahaha Or nostalgia purposes. XD My friend Barbara is hilarious to talk JRock to because she knows exactly Gackt, AnCafe, Dir en grey (which we don't talk about haha), and Baiser (kinda sorta; she got into them because of me and has found herself madly in love with Katsura XDDD).
I mostly feel lost because you talk about a lot of animes and mangas that I'm totally clueless about. It's like, I know we have some things in common, but I think it's hard to see them now, you know?
