Until recently, I had a house cleaning business and I went into homes that I would never even consider cleaning and I told the people point blank "I will not clean this place" because I knew that I'd come back in a week and the place would be filthy again. A lived in house is one thing; a place that's been neglected and people just don't care is quite another. I think it was cleaning other people's homes that made me even more aware of my own house and how it appears and smells to others.
