I saw Toph
immediately, but it's hard to me to explain exactly why... You look quite youthful, so maybe that's part of it. And maybe your hairstyle, a bit, in that first picture. I guess it's really just a vibe I'm getting, which is fine, because Toph is awesome. :)
Yay, green is my favorite color too! Maybe that's why Toph is coming to mind, because I associate her with the color green? ARRRGH! I just don't know how to explain it!
And don't worry about being obsessed with Avatar, you're not alone! I'm 23, and adore it! My husband too... we actually like it better than the kids we know, I think it's a really thoughtful show that's fantastically written, so it's easy for it to suck people like us in. :P
