I'd be interested! I enjoy playing teen characters, if that's alright. What if we did like a shy (younger) sister x outgoing (older) sister? I'd rather play the younger, if you didn't mind?
Also, I'm trying to get myself to be better at role playing, so sorry if I don't give excellent paragraphs. I can try to do two or three, if you want. But, I usually go for one. But, since I'm trying to be better, I'm willing to try harder. (:
