Actually, it does not take Asperger's. My Grandma A, my Grandma B [their real initials, which is rather neat]. Grandma A super neat - my mother who consiudered me a slob was too messy for her. Do NOT try to clean up, you will do it wrong and make a mess. My Grandma B super slob - even my sister [you cannot imagine] is no worse. You spilled the gravy on the rug? Leave it, the dog will get it and it adds color.
Me - one and the same - in one house I am visiting heap of garbage, in the other I am Mt. Ohsofussy.
It is not you - and not really her.. It is the interaction. I go places, I try to pick up after myselgf, I am not a total slob 0- but what is just right in one house is slopdike in the other and obnoxiuously pickjy in the third.
