Once there was an old man in a town. He always forgot a lot of things. So his wifealways had to say to him, " Don't forget this !" One day he went on a long trip alone. Before he left home, his wife said, " Now you have all these things. They are what you need for your trip. Take care of your things during the trip." He went to the station, bought a ticket and got on the train with it.. About half an hour later, the conductor began to see the tickets. He came to the old man and said, " Will you please show me your ticket ? " The old man looked for his ticket in all his pockets, but he could not find it. He was very worried. " I can not find my ticket. I really bought a ticket before I got on the train, " said the old man. " I believe you bought a ticket. All right, you do not have to buy another one." Said the conductor kindly. " But how can I know where I'm going ? I can not remember my station!" the old man said sadly. The old man bought the ticket  _   he got on the train.
