I went shopping in the center of the city yesterday afternoon. It was six o’clock before I was going home by bus. The bus was full of passenger, all of whom kept silent. A mother with her little son were sitting nearby. All of a sudden, the son cried loudly. The mother tries to do what she could make him stop crying. However, the son went on crying. After a long time, a man seating next to the mother said angrily, “Why don’t you give the child what she wants.” The mother answered quiet, “I would if I could, and what he wants is your hat.” Hearing of this, all the passengers burst into laughter.
