Hmm less about the characters I use to RP (I like making someone new-n-different each time) but I've got a whole cast of character who I keep around for no other reason than to fill sketchbooks with random tidbits. Initially, of course, I thought they would go to good use, but their stories are too bizarre to print since I started telling them in high-school and their lives took right-angle turns whenever mine did. But yeah, I even know everything about them, from what kind of swimsuit they own to what they did to get kicked out of university. :P
