....right now after the mania of Christmas?
1.You would need years of exposure to prepare your immune system to survive a visit. Could possibly feature on a TV show about cleaning.
2.Very messy but surfaces (kitchen and bathroom) have been regularly cleaned. You wouldn't want visitors but it isn't a danger to health.
3.Pretty much back to normal, a few Christmas bits are still hanging around but they will be gone in the next few days once the normal routine kicks in. Kitchen and bathroom surfaces are spotless and you wouldn't die of embarrassment if someone called in unexpectedly.
4.You could perform open heart surgery on your kitchen floor. The house is spotless and there is absolutely no sign that Christmas ever happened. Visitors are in awe of your skills as a domestic Goddess/God.
I think I am number 3, will aim to get closer to 4 next week (it won't happen!)
