It was the break time，and the students was playing on the playground．Jacky was playing the basketball with a group of boys while Lily told him that the headmaster wanted to see him．Jacky seemed confusing．He thought，"I did something wrong．Why did the headmaster ask me to his office？"Then he walked there nervously．In his surprise，the headmaster praised him，as he learned from some teachers that Jacky usually volunteered to helping others．The headmaster told Jacky he had set example for other students．Hearing that，Jacky was very happily．He promised the headmaster that he will continue to be a caring student．
