（）mother is a worker.

Soon, a golden-haired boy appeared. "Do you have a job for me？" he asked. I told him about a system for sorting books. He picked up the idea immediately. Then I showed him some cards for some unreturned books that I thought had been returned but not recorded. Maybe some books were put on wrong places. He said, "Is it a kind of a detective(侦探) job？" I answered yes, and then began his work.

He had found three books with wrong cards by the time his teacher opened the door and said, "Time for rest!" he argued for finishing the finding job, but the teacher won.

The next morning, he arrived early, "I want to finish these books," he said. At the end of the day, when he asked to work with me more often, it was easy for me to say yes.

After a few weeks I found a note on my desk, inviting me to dinner at the boy's home. At the end of a pleasant evening, his mother declared that the family would be moving to another school. Her son's first concern, she said,was leaving the library. "Who will find the lost books？" he asked.

The most fundamental group to which a person belongs is the family. The institution of the family exists in almost every human culture. It is considered by behavioral scientists to be one of the oldest institutions in human history.
