Once there lived an old man in a town. He always forgot things. So then he went out, his wife always said to him, 'Don't forget this.' One day he went on a long trip alone. He went to the station and bought a ticket. Then he boarded the train. About an hour later, the conductor began to check 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. 'I surely bought a ticket, but I cannot find it,' said the old man. 'I believe you bought a ticket. All right. You don't have to buy another ticket,' said the conductor kindly, but the old man still looked worried and said, ' If I don't find my ticket, I cannot remember my station. Where am I going?'
