Semyon Chebotarev lived a stormy life. I managed to serve a prison sentence and create my own business in the IT field. He got married, had children, built a house, grew a tree. Everything is as it should be. And he regretted only one thing - that he was not there when his mother died at the hands of his roommate. So, when I suddenly found myself in my own sixteen-year-old body in 2010, I was not at all afraid, but on the contrary, I was glad that I had the opportunity to correct my main mistake. That's just why there are red flags hanging all around, Marx, Engels, Lenin and Stalin looking sternly from the posters, and above the entrance to the House of Pioneers there is the slogan “Energetics of all countries, unite!”?
