It was five o’clock yesterday afternoon before I was going home by bus. The bus was full of passenger, all of who kept silent. A mother with her little son were sitting nearby. All of a sudden, the son cried loudly, the mother tried to do what she could make him stop crying. However, the son goes on crying. After what seemed a long time, a man seating next to the mother said angry. “I can’t stand it anymore. Why don’t you give him what he wants?” The mother answered quietly, “I would if I could. But what she wants is your cap.” Hearing of this, all the passengers burst into laughter.
