We do tend to accumulate a lot of junk - that's what our economy is built on.When I was a child, my parents had lots of things "that are too good to use" (antique chairs, silverware, an ancient reel lawnmower that didn't work, etc.) , so they hauled them from house to house and city to city.
When my sister and I cleaned out Dad's house, we gave away what we could, and threw out lots and lots of stuff. We both had to take weeks and weeks off work to get rid of stuff. It was overwhelming.
Thus, I am trying not to leave a lot of (material) stuff for my children.
