      Nate suffered a hard blow when he lost his job. His boss had spoken rudely, "Your services are no longer

needed." Nate left the building filled with despair. By the time he reached home, he was in a deep depression.

When he entered his house, he blurted out to his wife Sophia, "I lost my job. I am a complete, absolutely

failure." A tense silence followed. Then a smile crept across Sophia's face. "What great news!" she responded,

"Now you can write the book you have always wanted to write."

      "But I have no job and no prospect of a job," he objected, completely without hope. "If I struggle to be an

author, then what will we live on? Where will the money come from?" Sophia took her husband by the hand

and led him to the kitchen. Opening a drawer, she took out a box that was full of cash. "Where on earth did

you get this?" Nate gasped."To whom does it belong?" 

      "It's ours!" Sophia replied. "I always know that one day you would become a great writer only if you

were given the chance. From the money you gave me for housekeeping every week, I have saved as much

as I could so you would have your chance. Now there is enough to last us a whole year."

      What a surprise! What encouragement! What a wife! The unemployed husband did concentrate on writing

that year, and the novel he wrote became a literary masterpiece (杰作). The book is The Scarlet Letter. Sophia

had an even greater achievement, and she turned Nathaniel Hawthorne from a poor clerk into a world famous

master.
