Piles of possessions had taken over Mary Satterlee’s home. With 43 years of accumulation filling each room and spilling into the hall, she was ashamed to entertain friends and family but too overwhelmed to tackle the mess. “My house was a disaster. It was wall-to-wall, floor-to-ceiling-high stuff,” she said, describing how, when she tried to clear out the clutter in one corner, it would reappear as soon as she started the next. “It still accumulated more. I didn’t get very far up the road.”
