    Roy found a job in a factory. The manager and his father were good friends. The manager thought he must

give Roy an important position. So Roy became a gatekeeper.

    Roy worked twenty-four hours a day in the factory. He checked the bag of each worker when they left the

factory. He found nothing in their bags. He was very happy. Nobody took the products to his home.

    One day the manager asked, "Roy, did you find anyone took the products away?" 

    "No," answered Roy, "by the way, what products do the workers make?" 

    "Bags," said the manager.
