Describe/talk about your best friend

I would like to describe my best friend, Phong, whom I have known for roughly 11 years. I first met him at primary school when she was my classmate.  At first, he was quite shy and did not want to talk with anyone, which made me feel that he was a bit proud.  However, when we became close friends, she was more sociable and extrovert. We have done a lot of things together. Studying at the same schools, we have various mutual friends. So, we usually play football, go swimming at the weekends or have a picnic together. Besides, whenever I get into trouble, I turn to her for help. For example, I remember when I got bad marks in the exam, he consoled me and then we studied together until the official exam took place.  Finally, we had the opportunity to study at our favorite high school, which is called “CHV” At present, despite the fact that we have different plans and goals to pursue, I believe that we will be best friends for good and we will try our best to maintain this relationship.
