     Bill was fourteen years old. He had a part-time job which made him get up at five. He was a newspaper

boy. Though it was hard work, he enjoyed it a lot.

     Each morning, Bill left his house at five fifteen to go to the corner. The newspapers had been sent to the

corner by a truck at midnight. He always rode a bike to carry them.

     In winter it was still dark when he got up, but during the rest of the year it was bright. Bill had to send

the newspapers to the houses of people in all kinds of weather. He tried to put each paper in the box where

it would be kept safe from wind and rain or snow. His customers are in different places. Since many of them

worked during the day, Bill had to get the money at night. Sometimes Bill's customers gave him some more

money for his good work. When Bill was ill, his elder brother had to send the newspapers. Once, Bill's father

had to help him.

     Bill had 70 customers, but he hoped to get more soon. Some day, if he got many more customers, perhaps

he could win a new bike.
