Dear Mr. Rick,
Thank you for your kind letter of 01 March. I feel better now and am able to write this letter to you. The doctor said that I have gall bladder stones and I am scheduled to have my gall bladder removed in two days time.
If all goes well, the recuperation time will be about two weeks but it is up to the doctor to decide when I can get back to work. I prefer to work than to lie in hospital with nothing to do. Anyhow I have no choice in this and, as you say, I have to get well first before I can think of doing any work. But I shall be back as soon as I am able.
Once again thank you for your kindness.
