Sometimes, the family has a rummage sale:
Much of the stuff is out front because the garage is very much too full! Rummage sales (jumble sales, garage sales) are a big deal in some places.
We have an oversupply of goods
We have changing needs as we all age
We develop interests and we drop interests, often quite gradually
Fashions change and some things, colors, styles become become markers of by-gone times, history
We mostly want space but it would be nice to get some money for the goods as well. Should this t-shirt announcing a 1997 ski race go for $5 or $10? It is in good shape: no holes, no stains. http://fearfunandfiloz.blogspot.com/search?q=rummage+sale
