Please allow me to correct your paragraph. "Today, FOR the first time, I MET a foreign, English (Languages are always capitalized) teacher. He made us laugh and paid great attention to us, the students. His name is Paul, and he is from London, England. He talked WITH US about his work and life experience, and about the different places where he has traveled. He told us that his girlfriend is from Vietnam. He seemed very happy when he spoke of her. Today, he taught us SEVERAL things that HAVE IMPROVED OUR ABILITY TO speak English. I think that a foreing English teacher here in Vietnam will be WELL-RECEIVED BY THE PEOPLE, because THEY CAN HELP US FEEL CONFIDENT WHEN WE COMMUNICATE IN ENGLISH. (I hope this helps, and I welcome you to our language. It will be so useful and fun for you to become fluent in English. I became fluent and Spanish and it has been the most wonderful experience of my life, now I can travel and live in so many countries where they speak Spanish. Maybe one day you will go to England or America, or Ireland, and you can use your English with real people. I wish you the best of luck! It is wonderful to see your enthusiasm.... it makes our job a real joy, so thank you.)

I hope that you keep enjoying your lessons. Good luck with your studies!
