Importance of housework

I am usually very good about keeping my house clean, a task made much easier with my husband deployed. For some reason my housework doubles when he is home but I have to say I perfer more housework to him being gone. Now I do most of the housework after my son goes to bed. It usually takes less then an hour and I am very diligent, the toys are put away, the floor vacuum, dishes washed and put away, bathroom cleaned, clothes folded and put away, and the furniture dusted. I don't all those things every day except the dishes and the toys but rotate them through the week so that everything is done at least once a week. Everything but mopping the kitchen floor. I hate to mop. It does not take long but it is the thought of having to move everything off the floor, mop, let it dry, then return everything to the kitchen. If I am being good it gets mopped once a month. But then my son let me know the floor needs to be mopped once if not twice a week: he wants to eat off it.
