Write a Thanking letter to a Doctor after a successful Operation.
Dear Dr. Grover
I am very deeply indebted to you for that painless operation which you performed upon my ear last month. I cannot find words to thank you for extricating me from that excruciating agony. But for your timely help, I would have far preferred straight death to that crooked form of life-in-death existence.
I wonder if I shall ever be able to repay you
