When I was in China, there was a Japanese colleague named Satoshi in our company. He is 1.80 m high, good-looking, less than 30 years old, but looks a bit old. We seldom talked with him because he rarely laughed and we gave him a nickname "what things" (a homonym of his name in Chinese). Because I worked on the same floor with him, I met him often. He always looked lonely and unhappy. Maybe because he was lonely, he often worked overtime. He never went out with us or walked with any colleagues. We thought he deserves the loneliness because he left his hometown and came to work in China. But one day, there was an incident that changed my view on "what things". It was at noon, I was going out to eat with colleagues and we met him in the elevator. Because it was lunch time, the elevator was overcrowded as usual. When the elevator stopped at the main floor, there were a lot of people waiting outside to go up. As we hurried out of the door, I saw “what things” was standing by the door with his finger pressing on the button. When all the people went out, he still remained the same posture. I thought he was going to the garage downstairs but then I discovered that the elevator was ready to rise. I was so curious that I looked what in the end he wanted to do. “Does he forget something; ready to return to the office? What an idiot.” I talked to myself. I saw that he waited until the last person went into the elevator. Then, "what things" loosed his finger and dragged out of the elevator with his tired and motionless face. Suddenly, my colleagues and I looked at each other. Since then we call him Satoshi.
