Read the first part of the story and think. Cross out the words that are not important. Once upon a time, a man and his son went to town with their donkey. At first they walked. Some boys saw them. They shouted and laughed, 'Why are you walking? Ride your donkey!' So the boy rode the donkey and the man walked. Then a teacher saw them. He said angrily, 'You bad boy! Why is your father walking?'
