Dear John,
I am writing to thank you for looking after me after that unfortunate accident the other day, when I was knocked off my bike by a taxi. If it had not been for your assistance in giving me first aid and taking me to a nearby hospital, I fear that the consequences might have been much more serious.
The doctor says that my broken leg is healing well. In addition, the taxi company has agreed to pay my hospital bills. Everyone agrees that it was your quick-witted response in that Emergency that has led to this satisfactory outcome.
Although nowadays many people talk about the need to be unselfish and to help others, we see very few people practicing what they preach. But you showed by your actions that you are an exception.
Yours sincerely.
