Everyone is important
During Mark's first month of college, the professor gave his students a pop quiz. He was a conscientious student and had breezed through the questions, until he read the last one:
"What is the first name of the woman who cleans the school?" Surely this was some kind of joke. He had seen the cleaning woman several times. She was tall, dark-haired and in her 50s, but how would he know her name? He handed in his paper, leaving the last question blank.
Just before class ended, one student asked if the last question would count toward the quiz grade.
"Absolutely," said the professor. "In your careers, you will meet many people. All are significant. They each deserve your attention and care, even if all you do is smile and say 'hello'".
Mark never forgot that lesson. He also learned her name was Dorothy.
