Reality within even a simple bureaucratic structure may work quite differently from how the designers thought it. I mail a lot of packages. So some people modify procedures so they will work. Check out classroom teachers. The third implication in my example has to do with negotiation itself.
Life is negotiable.
Think of driving in any congested area. I live near one of the most car and people congested areas in the country, and by simply standing on the sidewalk I can observe life as negotiable. Money is also negotiable. That ain't hay. Time and money together are also negotiable.
