Polly greeted Walter and asked what was the matter. Walter replied that someone had stolen his bicycle and that it was the second time that year. Polly exclaimed, then said that her mother had seen a programme on television the day before. They had said something about a man stealing bicycles in their neighborhood. Walter surprised. Then he said that he had a friend who was a policeman and asked Polly whether he should telephone him. Polly answered that it was a wonderful idea and that she could drive him to work. Walter thanked her and said that it was very helpful of her.
