It is fascinating for me to observe this ordinary human behavior. The layers of papers have been my particular interest. At my parent' house in Tokyo, Japan, they make stacks of stuff everywhere. They save empty boxes, plastic containers, papers and almost everything, including small junky old toys which I used to play with. Now it is difficult to find a space to put their bodies.
Some people feel guilty about throwing away materials, finding that they are still useable.
If you visit Japan, you may find that people traditionally put things in containers or wrap them with nice papers. So those materials may end up accumulated in the corner of your room. Recently, I visited one of my printmaking professor's house to view the various piles. They have an amazing amount of materials that are stacked. It was interesting to look at the details, how they build all the little things together to create an effect in which you can find a repeated pattern of colors and textures.
