     Mark was walking home from school one day when he noticed that the boy ahead of him had tripped 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 articles. Since they were going the same

way, he helped to carry part of the burden. As they walked, Mark discovered that the boy's name was Bill, that

he loved video games, basebaii and history, that he was having a lot of trouble with his other subjects and that

he had just broken up with his close friend.

     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 talks, and then Mark went home. They

continued to see each other around school, had lunch together once or twice, and then both graduated from

junior high school. They ended up in the same high school where they had brief contacts over the years. Finally

the long last year came, and three weeks before graduation, Bill asked Mark if they could have a talk.

     Bill reminded him of the day years before when they had first met. "Do you ever wonder why I was

carrying so many things home that day?" asked Bill. "You see, cleaned out my locker because I didn't want to

leave a mess for anyone else. I decided to drop out of school. But after we spent some time together talking and

laughing, I realized that if I had left school, I would have missed that time and so many others that might follow.

So you see, Mark, when you picked up my books that day, you did a lot more. You helped me out."
