I went shopping yesterday afternoon. It is seven o’clock when I was going home by bus. The bus was full of passengers, all of which kept silent. A mother with her little son was sitting nearby. All of sudden, the son cried loud. The mother tried to do what she could to make him stop crying. Thus, the son went on crying. After a long time, a man sitting next of the mother said angrily, “Why don’t you give the child what he wants it.” The mother answered quietly, “I would if I could, and what he wants is your hat.” Heard this, all the passenger burst into laughter.
