It's sad, quite sad. This text is intended for amateurs, slackers, and generally frivolous people who still took the time to learn to read.The text of the book was translated from the original language using an artificial intelligence program. For the most part, the translation of the text is of very high quality, but in some cases, due to the imperfection of the technology, there may be incorrect phrase translations in the text, as well as single words and expressions may not be translated.
