    Kenyon Scudder once told me a story about his friend, Michael. Michael happened to be on a train sitting

next to a young man who seemed worried. Finally the young man told the friend that he was a prisoner

returning home from a faraway prison. His behavior had brought shame on his family, and they had neither

visited him nor written. He hoped, however, that this was only because they were too poor to travel and too

busy to write.

    When he was set free, he had written to tell them he wanted to go home. To make matters easy for them,

however, he had asked them to put up a signal for him when the train passed their little farm. If the family had

forgiven him, they were to put up a white ribbon in the big apple tree near the railway. If they didn't want him

to be back, they were to do nothing, and he would stay on the train, and go far away.

    As the train got near his hometown, his suspense became so great that he was afraid to look out of the

window. He asked Michael to watch for the big apple tree. They changed seats. In a minute, Michael put his

hand on the young convict's shoulder. "There it is," he said, his eyes filled with sudden tears. "It's all right.

The whole tree is white with ribbons."
