Dear George,
It’s been a week before we left your family and we are now back home. Thank you very much for showing them around your city and providing us for the wonderful meals.
After we said goodbye to you, we went to Washington D.C., which we stayed for three days. My brother was so much fond of the museums there that he begged my parents to staying another couple of day. However, my father had to return to work on Monday so we fly back last Saturday afternoon. It was really a nice experience.
If you’d like to make trip to our city some day, I will be more than happier to be your guide.
Yours
