Some things I obsess about:
My pantry. Everything is separated and all labels facing forward. Yes, the doors are glass and you can kinda see through them, so isn't it a good thing that I do this?
Folding towels (and all laundry for that matter). Everything is folded so it looks like it was ironed. Which brings me to my next obsession.
Ironing - Everything must be ironed before it is worn. And besides, its feels good putting it on when it is still warm.
My makeup and my jewelry - Everything is in its own little, neat divided tray, so I can see all of my selections - easily and quickly.
Steam-cleaning things. It doesn't matter to me - tile floors, carpet, couch, whatever. If my heated 5 scrubbing headed mean steam machine can reach it - I will clean it.
Hangars - Bill and my closet - wooden hangars. The kids plastic. Clothes are divided in sections and all hangars are the same distance apart.
I am sure there is more. I can thank my mother for teaching me to be this way, the short time she was here with us. Maybe my brother and sister will respond to this and add their own list. Chris - can you say "shampoo bottles"?
