Dear Mr. and Mrs. Stead,
This letter is a small token of my gratitude for the very warm welcome you gave me during my stay on your property. Indeed, you made me feel at home and treated me as if I were a close friend. I am reluctant to phone you because of my difficulty in expressing myself adequately in English; therefore, I am writing to you instead. Writing somehow seems easier than speaking.
Due to an unfortunate automobile accident, we left John in a rather unpleasant situation. I deeply regret that he had to return on foot and hope that he had no difficulty in doing so. I would have preferred that things had worked out differently. I hope the car will be repaired in time for the arrival of your new students. I offer you my sincerest apologies.
Once again, I thank you for a most pleasant stay. Because of your kindness, I can truly say that I now have nothing but the highest regard for your great nation.
With respect and affection,
