Some people—like Dimitri—live by the old adage 'everything has its place'. They like for things to be neat and in order; the bed is always made, their laundry is always folded and put away—not crammed in a drawer in a rolled up bundle—coats are always hung up—not draped across a chair— and things are put back where they belong as soon as they are used—as opposed to being left wherever it's convenient. They like their living space to be immaculate and completely clutter free.
The flip side to that coin… are the people like Rose Hathaway.
She rarely makes the bed—because in her opinion there is honestly no point to it when you're just going to unmake it again in a few hours—her dresser drawers are an overflowing mess, and her side of the closet they share makes the Russian cringe with its unorganized, half hung up clothing.
All in all, she is the complete opposite of her boyfriend, leaving things scattered about without consciously meaning to. Within a few hours of her arrival home at the end of the day, their neat, tidy apartment looks like a tornado came through. Dirty dishes are left on the counter, empty Coke cans litter the coffee table and her work clothes are strewn about, tossed on the floor wherever she happened to remove them. When Dimitri brings her attention to the mess she's made, Rose is always apologetic and promises to try harder to be a little less messy—and she really does mean to—but for some people, neatness just doesn't come easy, and no matter how hard they try, they just can't stick to it.
(Luckily Dimitri loves her enough to overlook this little flaw—and the fact she has an extra special way of making up to him for her messiness probably doesn't hurt either.)
