     Mark was walking home from school one day when he saw the boy in front of him fall over and drop

all of the books he was carrying, along with two sweaters, a basketball and a walkman (随身听). Mark

stopped and helped the boy pick up (捡起) these things. Since they were going the same way, he helped

to carry some of his things. As they walked, Mark knew that the boy's name was Bill, that he loved

computer games, basketball and history, and that he was having lots of troubles with his other subjects

and that he had just broken up with his girlfriend.

    They arrived at Bill's home first and Mark was invited in for a Coke and to watch some television. The

afternoon passed happily with a few laughs and some small talk, then Mark went home. They often saw

each other at school, had lunch together once or twice, and then they both finished middle school. They

ended up in the same high school where they sometimes saw and talked with each other over the years.

At last just three weeks before they finished high school, Bill asked Mark if they could talk.

     Bill asked Mark if he still remembered the day years ago when they had first met. "Did you ever think

why I was carrying so many things home that day?" asked Bill. "You see, I cleaned out my locker (锁柜)

because I didn't want to leave anything for anyone else. I had put away some of my mother's sleeping pills

and I was going home to kill myself. But after we spent some time together talking and laughing, I began

to understand that if I killed myself, I would have missed (错过) that time and so many others that might

follow. So you see, Mark, when you picked up those books that day, you did a lot more. You saved

my life."
