It had been a long, hot and muggy Chicago summer. I was the principal of a private school that had decided to move to a new building, and I had spent countless hours over that summer overseeing the move. Unfortunately, I was not the only one whose summer was significantly disrupted. Each teacher was busy boxing his or her classroom materials, a task that could not commence until school had let out. It was a tedious job that did not do much to enhance teacher morale.
