If my kitchen floor is a little dirty when you visit tonight?

Or if my dishes aren't done but are covered with a dishtowel until later?

If my sitting room is less than perfect?

If my toilet hasn't been flushed (water restrictions, but still ...)?

If my home is mostly uncluttered but I still bother that you are going to think I am messy / or untidy / or God forbid ........ dirty?

Why do these things matter so much?

My husband tells me that I am wearing the walls, floors and carpets right down with my constant cleaning. I reply that there could be an unexpected visitor.

Why on earth does it matter so much, and what difference does it make anyway?
