My niece and I were roommates for about 8 months, and that was all I could take, as soon as her lease was up I moved out. She would go into my room and I knew it because she would not always close the door and her darn cats would be asleep on my bed or in the window. When I would ask her about it she would admit that she would go into my room to make sure I was keeping it up to par. Like I told her as she already knew it was spotless and stayed that way until her cats would leave cat hair. She had 4. Boy was it nice and quite when I moved into my own apartment. And I did move in to help her out as her other room mate left her in a bind. I did not have to move in with her.
