Following the publication of the article "A Tale of the ugly duckling," I received an interesting letter from Andrei Bystritsky. We struck up a correspondence. In total, we exchanged 5 6yu letters. With the consent of Andrew I decided to publish it. The first letter I quote in full. The remaining letters I cut on the lines and everything was looking like a live conversation between two people: Andrew Bystritsky (AB) and Andrew Knyazev (AC). The text of the letter was not edited! Correct only grammar errors:)!
So, start! Here is the text of the first letter!
