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. But for your assistance, I fear that the consequence might have been much more serious.
The doctor says that my broken leg is healing well, and that I would be able to stand up again in a week’s time. In addition, the taxi company has agreed to pay my hospital bills.
Anyway, everyone agrees that it was your quick-witted response in that emergence that has led to this satisfactory outcome(满意的结果). I feel I owe you so much, so please accept my most sincere thanks.
Yours sincerely,
Li Ming
