Dear Mary，
I would like to take this opportunity to express my heartfelt gratitude to you for your help when I was in difficulty. You have been very kind and helpful since we knew each other.
Last week， I caught a bad cold and had to stay at home for a week. When I was worrying about the lessons， you came to my home after school and helped me with every subject. With your help， I didn't fall behind others.
Again， thanks so much for your enthusiastic help. Even though you are to about to go abroad for further education I know that I will always stay in touch with you. I wish you every success in the future and I hope we can exchange more viewpoints on study.
Please keep in touch， and drop in and visit us whenever you are in this part of the world.
Very sincerely
Peter
