Dear Robert,
Thank you for your letter, we arrived home without accidents. On the way we stopped twice to take pictures for memory. I really liked your city. It is very quiet sometimes it seemed to me that there are no other people. Most of all I remember how we went with your father on a hunting trip. Thank you for all that you and your family did for us. I really hope that you come to us for the new year, I have already started to plan a route where we should go.
Best wishes
Igor.
