Before I was 12 years old, my family lived in the mountains.<br />Our house was far from my school. It took me one hour to walk to school every morning.<br />It was a happy time for me because I could meet friends on the way,<br />and we would go to school together. There were just six classes in my school,<br />and only about 20 students in each class. We spent most of our time playing.<br />The mountains were our playground. I still remember the different kinds of flowers,<br />the songs of different birds, and the colors of trees in different seasons.<br />Everything was so interesting and beautiful. Even now I still miss my life in the mountains.<br />Before I was 12 years old, my family lived in the mountains.
