I've had some pretty bad experiences with roommates that were chosen for me. Not that we didn't get along in the long run, but they weren't very considerate about my things and stuff. Though I've had problems with roommates I chose myself too so it's really difficult either way.

Well, it's half tumblr half not. A couple of interviews have stated that Teddy is going to fall on hard times(this is AFTER the whole evil!mom thing) and worse things will end up eventually happening to him.
