A lot of us have way too much disposable odds and ends--I don't even want to tell you how much tech logo clothing I've ended up with over the years. But not everything needs to be pass down to your grandchildren quality.
But yeah most grandchildren auction off their parents belongings anyway. That’s why birds make nests and then they go somewhere else and maybe return, make a new nest.
People are fixated on permanence—perhaps that’s another way to build housing: design it so it is sustainable, then tear it down and recycle the materials every 10 years.
