scary messy

we all know the definition of neat, but what exactly constitutes too messy? how messy does one have to be to be considered scary messy?
messy is piles of papers all over but no apple cores on the floor or food anywhere outside of the fridge or kitchen cabinets unless one is eating a meal. food or goopy dirt everywhere constitutes dirty.
i am not as neat as i would like to be, but ive seen other friends' housekeeping skills and id say many have apartments that make me feel like im in my own home. i have never gotten so out of control that i would not invite a friend over.
scary messy is yet another level. its the level where one never lets anyone, not even close friends, into one's apartment. i suspect that i have a few friends or acquaintances who keep house scary messy because they will never let anyone besides themselves see the walls of their abode. heck, they know how i dont keep house. if they are still embarrassed for me to see their dwelling, well they are indeed scary messy housekeepers.
though i will never have a home as organized as martha stewart, i will say when im most at peace with the world my apartment is more organized. when im less enthused with life, my organizational skills peter out. much as i hate to admit it, this connection exists. this is why i pity the scary messy so. they are so far gone in more ways than one that their homes become scary messy. they are too weak to clean up after themselves, but have enough self respect not to invite anyone else into their mishmash.
