A Fateful Place for a Meeting

- Do you know whom you are speaking with - Woland asked the newcomer - and whom you're currently visiting?
- I know - replied the Master - my neighbor in the mental asylum was this boy, Ivan the Homeless. He told me about you.
- Of course - Woland responded - I had the pleasure of meeting this young man at the Patriarch's Ponds. He almost drove me insane, proving to me that I do not exist! But you do believe that I am real?
 - I am forced to believe - said the newcomer - but, of course, it would be much safer to consider you a fruit of my hallucinations. I apologize - realizing what he had just said - added the Master.
