Since I disparaged my daughter's housekeeping, thought I'd post a bit my own (or lack thereof).
I took this picture of my floor after my daughter pointed out that we had a hidden mickey in our kitchen. I only mop when company is coming over, or the floor is so sticky that the cats are stuck to it. Gross, I know. When I was a "real mom" I used to scrub my floor weekly on my hands and knees. Now, my days off are devoted entirely to laundry and shopping. Mopping is really low on the priority list for me.
On the plus side, my kids have something fun to do - finding hidden pictures in the crud on the floor.
