From 65438 to 0965, I worked as a librarian in a school library in Washington. One day, a teacher in charge of teaching nine-year-old children's class came to me and said that one student in her class finished his homework faster than all the other children. He wants to find another job and can do something in the library. I said, "Let him come." After a while, a little boy with light yellow hair came in. He asked, "What do you want me to do?"

I explained Dewey's decimal book classification and shelving method to him, and he immediately got the message. Later, I showed him a big stack of expired library cards. At first, I thought the books on the library card had been returned, but in fact, due to the mistake of the library card, these books could not be found. He asked me, "Is this a detective's job?" I replied, "Yes." As soon as his voice fell, he began to work like an invincible detective. When the teacher came in and told him it was time to rest, he had found three books with wrong cards. He refused to have a rest and insisted on finishing the work first. The teacher said that the air in the museum is not good and he should be given some fresh air. Only then did he stop working. The next morning, he came early. He said he would finish looking for books. After work, he said he wanted to be a full-time librarian, and I readily agreed, because he worked tirelessly.

A few weeks later, I found a message on my desk inviting me to the boy's house for dinner. I was invited and had a good time. When he left, his mother said that the whole family would move to the neighboring community and the children would transfer schools. But the child's first concern is that he can no longer work in the library of the original school. Who will find those lost books?

The child is leaving, so I will say goodbye to him. At first, I thought he was an ordinary boy, but his enthusiasm for that job made me think he was extraordinary.

I miss him very much. But this yearning didn't last long, because a few days later, I didn't expect him to come back. He told me that the librarian of the new school wouldn't let students help in the library. He said happily, "Mom asked me to go back to my old school again. Dad asked me to take the bus on my way to work. If he has something to do, I will walk to school. "

At that time, an idea flashed through my mind: the child's determination and perseverance are so great that he will definitely make a difference in the future. However, I didn't expect that he would become a wizard in the information age, a giant of micro-software and the richest man in the world when he grew up. His name is: Bill? 6? 1 door.
