Disposable Art

In psychiatry, patients are sometimes asked to abstract -- to complete a maxim, explain what it means, etc. Those who can't are "concrete" and may be suffering from an organic brain disorder, or schizophrenia.

One common test of abstraction is to explain what this means: "people in glass houses shouldn't throw stones."

I've heard answers ranging from "it's like shooting yourself in the foot" ... to "you'll break the walls" ... to "people are watching me!"

I just hope a paranoid patient never walks into this structure.

Sheesh, I have a hard enough time going when there's someone in the adjacent room.
