When I was 12, I met Jane in a college, which came to China with her parents. Her parents teach English at that time. We soon made friend with each other. Her Chinese was very well while I had difficulty speak English. In order to help me my English, she spoke as much English as she could when we were together. Before long, I could speak English well but at the same time I also made a great progress in my written English. Unfortunately, a year later, Jane returned home with his parents. And we had been out of touch with each other since then.
