I know,,,It only takes on visit to take the little guys home with you. I went to LA to meet up with my kids. I stayed at a hotel that appeared to be very clean. When I got to the room, I saw a spot on the bedspread. I called housekeeping an stayed with them as they changed the bedding. People think I am nuts when I pull the mattress away from the frame. If there is dirt there, they can have their room back. I will sleep in the car. My room was spotless before they left.
