We clothe ourselves.
We bathe and groom.
And we make love, and laugh, and cry.
We read and talk, tell stories.
Sometimes we even sing.
Maybe dance a bit.
What are we sheltering from? Heat and cold, wind and rain, yes. But also from people. Our exterior advertises, while the interior disguises. There is an idea of access and intimacy as well. How far will you be allowed into our lives?
Which goes back to—how public is a particular activity? Each room must meet a mechanical, psychological, and social need. Closets and cupboards meet a psychological need for security. This is also social—a guest shouldn’t see any more than they need to see.
