   Dear Ms Lily,

   Many thanks for your kind letter and lovely photos of my vacation in America. Sorry for the delay in replying to your letter, but your package arrived just as I was about to leave the city on business. I just returned to Vietnam today.

   Looking at the photos brings back so many happy memories of the time we spent together and the wonderful hospitality you gave me. I find this trip very interesting! You guys surround me with warm friends, delicious food, great sights, great shopping, unforgettable cultural events and laughter-filled evenings. I would have lost it without you. I sincerely thank you.

   Good memories gave me an idea. I know you always wanted to visit Vietnam. Why don't you plan a vacation and stay with me this summer? The weather is great that time of year, all the tourist attractions are open and I can take you anywhere you want. In addition to seeing the tallest tower in Vietnam, we can drive you to other more interesting attractions and tourist attractions. I would be happy if you could come.

    Thank you again for the beautiful stay and the beautiful photos posted on my page. Now, I look forward to hearing from you.

                 Warmest wishes for you

Study well!
