silly as it sounds I think Cindy is just a neatnic. Cindy was hating the clothes not put away in Casey's room, kept them there until she could stand it no more.
Look at their garage...floor is painted so that there are no stains, most things appear boxed and labeled. On Greta she apologizes or makes excuses for the part of her yard that she feels isn't up to standard.
The decorations in their home seem pretty clean, meaning not cluttered and such. The walls are all white, the home is painted in light colors. The 97 pontiac looks pretty darn clean for a car of it's age.
She talks about checking the pool daily (filters and such). Her dogs fur looked clean and shiney. Odors bother her, like smoke.
Caylee's room was very organized, high built-in shelves for the books, a hanging home for stuffed animals. Caylee's bed had pillows knocked off by the dogs, she picked them up right away.
She closes one side of the shed after a reasonable amount of time b/c imo she felt it isn't organized enough....like letting someone look in your 'junk drawer'. Casey's room is well organized.
I think Cindy was a loving and attentive mom, she took care of her children and perhaps too well. She was just being mom by washing dirty pants of her wayward daughter, they smelled and just reminded her of how Casey was living and perhaps her gd.
I don't think she thought in a million years her daughter could have possibly killed her grand daughter! She just shuddered at the thought of Caylee living in some smoke filled home with a bunch of slobs. She just wanted to clean up because that's her routine and what she does naturally. jmo
