I was in San Francisco a couple of days ago. As I was leaving the hotel there were a lot of people coming in and out of the front door. And, as it happens most mornings, people were preoccupied, struggling to get to work. There was tension in the air. As I opened the door, I slowed down to let an elderly gentleman in. He looked at me, straight in the eye, and said "Thank You." That made my day!
In this fast paced world we live in, it's a good reminder that two words still have amazing power.
