To me commenting a fic you enjoy it's a way to thank the author for taking the time to write down and/or share with us the story. So, although I'm a sucker at leaving decent comments and I'm a lazy bitch, I try to leave the more comments I can.
Ok, I never commented your fics but... ._. I find myself commenting only fics on LJ because it's very fast that way. *hmm*.

Anyway, I love to death the fics or yours I read until now. I probably have already said in older comments to a post of yours but, hey, let's pet your ego a bit, you deserve it! XD
