"Years ago I had a conversation with a man who told me that the most important truth he had learned was to be kind. He learned this, he recounted, during a cab ride in New York City. As he was paying the driver, he said, 'Thank you, sir.' At this, the driver leaped, ran around the back of the cab, and opened the door for his passenger. Startled, the man got out and said to the cab driver, 'You didn't have to do that,' to which the driver responded, 'I wanted to. You are the first person in this country to honor me by calling me sir, and I thank you for that respect.' The man had never before considered the power inherent in a respectful gesture, but from them on, kindness became the pillar on which he built his life and the legacy he hoped to pass on to his children. That exchange, he said, changed his life."
