recently, i got to know a foreign net friend who is a canadian, friendly and loving to learning chinese. we began to exchange language, although we both do not good at foreign language, just by encouraging each other, we also can understand well and chat very happy. if i make some wrongs, the other one can help you correct them. don't be shamed about your mistakes, we are not perfect. During a period of talking, we found many characters in common between us. but the more important is we can learn more, not only language but also culture and friendship. and my confidence also come back to me. i do not fear speaking out before my boss any more. it is a great progress to me. i will keep on.
