I arrived at a little town late at night and felt too tired to drive any further so I went to a hotel. "Could you give me a room for the night" I asked a lady at the front desk ."I am sorry," she said, "You should have booked a room earlier. If you had, it would have been all right. But now every room is full. I wish I could suggest somewhere else but this is the only hotel in town and every room was booked up weeks ago." "What a pity!" I said, "I have been traveling since breakfast and I am very tired." "Well," she said kindly, "Before you give up completely, let’s look at the record of the list. Someone might have changed his plan. Yes, here is a telegram. ’I am arriving on the 7th instead of the 6th.’ You can have this gentleman’s room for the night.\ The lady know there was a free room from someone’s telephone.
