The Million Dollar Question

We had guests stay with us just after the holidays.   This meant that in addition to holiday preparations and my busiest time at work, I was mired down in housework in an effort to get our place looking presentable for company.    The husband helps, but let's face it, his standards are a bit less stringent than mine. 

After our relatives were gone, it seemed to take no time at all for the house to look "lived in" once again.   This usually frustrates the snot out of me, but I've learned not to let it ruffle my feathers too much.  But still, I would love to know ~ how is it that two people, who have no children and no pets, and who spend more time away from home than in it, can make such a mess??
