It was Christmas, and there was a big party in the house. Guests came and went, but the party went on. Then the bell rang. Several people shouted, "Come in!" and a small man opened the front door and came in. Nobody knew him. But the host went to meet him, and took him to the bar for a drink. The man sat there happily for an hour and drank. suddenly he stopped and looked at the host. "Do you know," he said, "nobody invited me to this party. I don't know you, I don't know your wife, and I don't know any of your guests. My wife and I wanted to go out in our car, but one of your guests' car was in front of our gate, so I came here to find him and my wife is waiting in our car for me to come back. "
