     A poor boy became a rich and famous singer. He married and had two sons and two daughters. One day

he said to his wife, "Our children mustn't have a hard life as we had. We must help them more than our parents

helped us." The wife agreed.

     So they sent their children to fine schools. They enjoyed expensive sports. They were given everything in

life except this: they were not taught how to work. Later the parents bought businesses for their children. The

sons, at 21, became the owners of banks. The girls were given shops. But soon all these businesses failed.
