Mark was walking home from school one day when he noticed the boy ahead of him had tripped(绊倒)and dropped all of the books he was carrying, along with two sweaters, a baseball bat, a glove and a small tape recorder．Mark knelt down and helped the boy pick up the scattered(散落的)articles．Since they were going the same way, he helped to carry part of the burden．As they walked Mark discovered the boy’s name was Bill, that he loved video games, baseball and history, and that he was having lots of trouble 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 pleasantly with a few laughs and some shared small talk, then Mark went home．They continued to see each other around school, had lunch together once or twice, then both graduated from the junior high school．They ended up in the same high school where they had brief contacts over the years．Finally the long awaited senior year(大学最后一个学年)came and three weeks before graduation, Bill asked Mark if they could talk．
Bill reminded him of the day years ago when they first met．“ Did you ever wonder why I was carrying so many things home that day?” asked Bill．“You see．I had stored away some of my mother’s sleeping pills(安眠药)and I was going home to commit suicide(自杀)．But after we spent some time together talking and laughing, I realized that if I had killed myself, I would have missed 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．”
