Here came the day when they took the final interview. A big box of papers was placed on the way to the interview room, and a few papers were lying around the box.
The first student came. He hurried along the way to take the interview. “Who put this in the middle of the road?” the student said to himself, but he did not try to move the box away. Instead, he passed around the box and continued his way.
The second student came along and did the same thing. Then another came, and another. All of them complained (抱怨) about the box but of them tried to move it. What's worse, someone even stepped (踩) on the papers and left without having a look at the things on the ground.

Without thinking twice, he and began to pick up the papers and put them into the box. Then he managed to move the box to the side. To his great , he found an invitation under the box. On it were the following words, “Congratulations, young man! You are the person we are looking for! Would you like to join us?”
