A man stood at the glass door of a department store early in the morning, with the intention of entering. The door wouldn’t even open an inch. He tried to push against it, but nothing happened. He could have knocked or called. He could have tried to open the door by force. The man did none of these. He looked at the sign with the opening times, looked at his watch, and then went for a walk for about ten minutes. Then he came back and stepped in front of the door. The door now opened all by itself, automatically and as if from the hand of a ghost.
