One day, a strong man went for a walk in the park. He saw a thief take a bag from a lady. The strong man said, "Stop! Give the bag back!" The thief did not listen and ran away.
The strong man ran after the thief. He was very fast. The thief had to pause to catch his breath. The strong man said, "You are bad! Give the bag back now!" The thief shook his head and ran away again.
The strong man tried to catch the thief, but he was too tired. The thief got away with the lady's bag. The strong man was sad. The lady was sad too. The thief was happy, but he was still a bad person.
