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 a half and drank.Then 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' cars 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!" How long did the small man stay at the party?
For an hour. For half an hour. For 90 minutes. For a while.
