These really and truly happened:

1.  Porn streaming on the desktop computer 

2.  Naked seller asleep in a bean bag chair in the family room

3.  Divorce papers left out on the counter in the kitchen

4.  Seller rear ended a parked car in the neighborhood while house was being shown

5.  All of these happened on the same appointment.  

So, if your house is on the market and you have a surprise showing and you forgot to make your bed, it's ok.  Really.  Realtors have seen worse!
