There is a dialogue between a doctor and a patient about illness.
Myself: May I come in, Sir?
Doctor: Yes, come in. Please have your seat and let me know your problem.
Myself: Thank you. I have been suffering from fever for a week. I need an immediate cure as my exam is near at hand.
Doctor: Do not get worried. Everything will be alright. Let me check you up thoroughly.
Myself: Along with my fever I have cough also.
Doctor: Okay, I see. What are the signs of your fever? When do you feel temperature high?
Myself: It is usually 5 pm to 10 pm.
Doctor: Do you feel any shivering sensation then?
Myself: Yes, I do.
Doctor: Do you get thirst then?
Myself: Yes, I get. I wish I could drink very cold water.
Doctor: Did you take any sort of treatment previously?
Myself: Yes, I was under the treatment of a village quack.
Doctor: Please, show me the prescription.
Myself: Here it is, Sir.
Doctor: Oh, I see. He has prescribed you wrong medicine. Yours is malaria but he has given you the medicine of typhoid.
Myself: Strange, indeed!
Doctor: Yes, let me prescribe you some right medicines.
Myself: Thank you, Sir.
Doctor: You are most welcome.
