As bearisgray said, beds made and dishes washed and put away.
I do the floors when they get crunchy (have 2 cats so cat litter can be an issue).
TxDot is rebuilding and increasing the lanes on the freeway close to my house. Even with windows closed we get a lot of dust so I don't bother to dust unless company is coming and then only minimally - at least that is the excuse I use for not dusting.
I can't remember for sure but I think it was Phyllis Diller who said to keep some get well cards to put out when company came so they would think you had been ill and not able to clean. A friend of mine used to keep cleaning supplies in a bucket and when her mother showed up would greet her at the door saying she was just getting ready to clean. She would vary it with the vacuum cleaner or broom and dust pan.
My philosophy - as long as I am happy and the health department is not knocking on the door, it is good!
