John and Bobby joined a wholesale company together just after graduation from college the same year. Both worked very hard. After several years, however, the boss promoted (提升) Bobby to the position of manager but John remained an ordinary worker. John couldn't understand it anymore, gave his resignation(辞呈) to the boss and complained that the boss didn't value hardworking workers, but only promoted those who flattered (奉承)him.

The boss knew John worked very hard for the years. He thought for a moment and said, "Thank you for your criticism(批评), but I have a request. I hope you'll do one more thing for our company before you leave. Perhaps you'll change your mind and take back your resignation."

John agreed. The boss asked him to go and find out anyone selling watermelon on the market. John went and returned soon. He said he had found out a man selling watermelon. The boss asked how much per kg? John shook his head and went back to the market to ask and returned to tell the boss$1.2 per kg.

Boss told John to wait a second, and he called Bobby to come to his office. He asked Bobby to go and find anyone selling watermelon on the market. Bobby went, returned and said,"Boss, only one person selling watermelon. $1.2 per kg, and $ 10 for 10 kg. He has 340 melons in all, 58 of which are on the table. Every melon weights about 2kg. Bought from the South two days ago, they're fresh and red, good quality."

John was very impressed and realized the difference between himself and Bobby. He decided not to resign but to learn from Bobby.
