Jake would probably just chill by himself, so he could easily have a room. I'd play video games with Marco, make a drawer nest for Tobias, and show Rachel the awesomeness that is online shopping. Cassie might be a problem....I can see her going to bed at like 9 pm and yelling at me for playing my music too loud because she's trying to study. Ax might also be a problem....I'd have to go grocery shopping every other day. And, you know, the hoofprints on my bathroom floor.
