I always remember the sad memories at the end of 5th grade. We had to say goodbye to each other to go to a new grade. My best friend moved away with her parents. We grew up together, went out together, went to school together, had a lot of good memories together. Dang Khoi once told me that they would go to the same school together to continue going to school together. But we had to say goodbye to each other. The day he moved away, I cried a lot because I could no longer be close to each other. Now we have little contact. The geographical distance is too far for us to meet each other. However, I still hope you will study well and hope that we will meet again in the near future
