It has been ten years since I graduate from high school. Last week, I informed of a class
reunion held by our monitor unexpected. Much to my delight, most of his classmates got
reunited, recall the time we spent together. In addition, many activities were arranged, one of that was to visit our school and teachers. It reminded us of the excited moments we enjoyed
together. All of us thought it was the huge success. Despite of being separated, I will never forget my dear classmates or always keep the precious memory in mind.
