I didn’t want to post this text - it’s a little damp, in my opinion. But my fantastic book simply caused gnashing of teeth among the “Kalash-our-fsyo-MTK-genius” fans, so I had to answer in detail. Consider this a kind of extended note, or something... Yes, if someone wants to challenge it, feel free to do so, just without impudent rudeness, be so kind! Well, who “knows everything already” - just don’t open it, you’ll be calmer, you need it - be nervous about all sorts of nonsense?
