There was once a man who spent all his time in his glasshouse. Flowers was his name, and flowers were his main joy in life. He grew flowers of every color under the sun. He grew these flowers in order to enter them for competition. His greatest hope in life was to grow a rose of an entirely new color that would win him the silver cup for the Rose of the Year.
    Mr. Flowers’ glasshouse was close to a public path, which was always used by children walking to and from school. Boys were often attracted to throw a stone or two at his glasshouse. So Mr. Flowers did his best to be in or close by his glasshouse at the beginning and end of the school day.
    However, it was not convenient or possible to be on guard all the time. Mr. Flowers had tried in many ways to prevent harm to his glasshouse, but nothing that he had done had been successful.
    Then, just as he was giving up hope of ever winning the battle, and of growing the Rose of the Year, he had a truly wonderful idea. He put up a large notice made of good, strong wood, some meters away from the glasshouse, where it could be clearly seen from the path. He had painted on the board the words: DO NOT THROW STONES AT THIS NOTICE. After this, Mr. Flowers had no further trouble. The boys were much more attracted to throw stones at the notice than at the glasshouse.
