The book starts with a story of a college exam for which students had more-than-adequate time to prepare. Nonetheless, there was moaning of the highest (lowest?) order as students got to the last question. Which was … “What is the first name of the man who cleans our school?” Damn few, or fewer than few, aced that one. The prof explained, “As you go forward in life, you will meet many people. All of them are important. No matter what their position, everyone you cross paths with deserves your attention and respect, even if all you do is just smile and say hello.”
