I am also childfree. I don't mind a bit of chatter about kids but if that's all you write about then nuh-uh, no. And I'm an Australian, born in Poland, Aussie since I was 5 :) And I'm a massive book fan :D
What I look for in a friend:
1. open minded - if you are anti-gay, anti-choice, racist or a religious psychopath, no thanks.
2. Likes animals :)
3. Look, I'm not a huge fan of fan-fic, don't mind it in on LJ as I just skip through and I know it brings people a lot of pleasure, but just yeah no if that's all you post.
4. Be yourself :)
