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. In       
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.
