Christie was one of my best friend at my high school. At that time, we often spend time together. Thank to her help, I made a great progress in my study. Last year, she decided to study board. In another words, we would be separated for a long time. Before her leaving, I prepared a gift to show my best wishes to him. She said it was the best gift she has ever had. From then on, we’ve kept touch with each other through e-mails. I look forward to see her again in the near future.
