Mark was walking home from school one day when he noticed a boy ahead of him. He had tripped(绊倒) and dropped all of the books he was carrying, along with some clothes, a baseball bat and a glove.

Mark knelt(跪) down and helped the boy pick up the things. Since they were going the same way, he offered to carry some things for the boy.

As they walked, Mark discovered the boy's name was Bill. He loved video games, baseball and history, but he was having trouble with some of his subjects.

They arrived at Bill's home first.  Mark was invited in for a Coke and to watch some television. The afternoon passed pleasantly with some laughs and talk. Then Mark went home.

Bill reminded(提醒)Mark of the day years ago when they had first met. "Did you ever wonder why I was carrying so many things home that day?" asked Bill.
