Doctor: Mr. Rahman, shouldn’t you have come to me two days ago?
Mr. Rahman: I’m sorry doctor. I was so busy that I had hardly any time to see you.
Doctor: you must not have been as busy as I (am), I can say.
Mr. Rahman: Maybe I wasn’t. But I have been two days late.
Doctor: you have contacted two more diseases these two days. Do you know it?
Mr. Rahman: no I don’t. If so, how to get rid of them?
