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
