你好！我叫杜書文。我是美國人。我的太太和我正在學習中文。我們是英文老師。I can help you with your English and／or Spanish. I am looking for a native Mandarin speaker who is interested in participating in an on going texting conversation just to have some regular exposure with my target language. I am happy do the same with English. We can discuss everyday topics and answer any questions about the our target languages and correct each other's mistakes from time to time. PM me if you are interested. 謝謝
