Earlier today, I was sitting on a park bench eating a sandwich for lunch when an elderly couple pulled their car up under a nearby oak tree. They rolled down the windows and turned up some jazz music on the radio. Then the man got out of the car, walked around to the passenger side, and opened the door for the woman. He took her hand and helped her out of her seat, guided her about ten feet away from the car, and they slow danced for the next half hour under the oak tree.
