    Watson entered Mr. Smith's office. The boss was a hard man. He fired people who didn't do well without giving them a second chance.

    “Watson, ” said Mr. Smith, “this past year your department hasn't earned money. We're going to drop that department. It's finished. I'm sorry, —but you'll have to go.” “But, sir—if I just had a little more time. For the moment I need the job to keep my son at Riverside School.”

    “What's that!” said the boss. “Riverside! I didn't know you had a boy there. That's an expensive school for a man with your salary.”

    “I know, sir. But he likes it there so much!He's a star athlete and the best boxer in the school. The boys call him Champ (冠军) there.”

    The boss sat perfectly still for a long time—a faraway (恍惚的) look in his eyes. Then, suddenly, he said, “We've got to close your department, Watson. But you'll take over a new job in another department. It means longer hours—maybe more pay. Now get out. You're here for life.”

    Watson got out, with surprise on his face. Then the boss took a letter from the top drawer of his desk. It was Herbie's last letter from Riverside School—written a few days before he died. He had read it over and over again with sick pain. The letter read:

    I can't say the boys here are any nicer to me than the others were. I guess it's the same everywhere when you're a cripple (跛脚的人).

    But don't worry about me, Dad. They've got a good chemistry department here. And there's one boy here who is really great. He's a track star and boxing champ and just tops in chemistry. The boys call him Champ. He made them stop throwing my books around. And he knocked a boy down who hit me. He is the best friend I ever had. Dad, when I grow up, I want to do something for Champ. Something big—that he won't even know about.

Your son

Herbie
