If you've already gone thorough this I'd like to hear from you too.
In the 18 months of my mothers decline I often found my self wandering the house in the middle of the night looking at the house and all its possessions. I came to the conclusion that there are about ten things in the house I would consider keeping. Out of a lifetime together they have acquired thousands of things. Closets full of clothes that the haven't touched in years, possible decades. File cabinets of papers that have no discernible purpose. Vehicles that may still have the random M&M in them from the 1980's. So much stuff. How did they get this much stuff?
