A police car pulled me over near the high school where I teach. As the officer asked for my license and registration, my students began to drive past. Some honked their horns, others hooted, and still others stopped to admonish me for speeding.

Finally the officer asked me if I was a teacher at the school, and I told him I was.

"I think you've paid your debt to society," he said with a smile, and left without giving me a ticket.
