     Christie was one of my best friend at high school. 
At that time, we often spend time together.       
Thank to her help, I made great progress in my   
study. Last year, she decided to study abroad. On 
other words, we would be separated for long time. 
Before her leaving off, 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.
