Christie was one of my best friend at high school             76      
At that time, we often spend time together.                   77      
Thank to her help, I made great progress in my                78      
study. Last year, she decided to study abroad. In             79      
other words, we would be separated for long time.             80      
Before her leaving off, I prepared a gift to show             81      
my best whishes to him. She said it was the best              82      
gift she has ever had. From then on, we’ve                   83      
kept touch with another through e-mails. I                    84      
look forward to see her again in the near future.             85
