In this autobiographical work, the author talks about school hooligans in the mid-60s of the Soviet period of the country's existence. He is trying to understand the very concept of “hooliganism,” how it influenced the development of a teenager, and whether it is dangerous for his future. The author tried not to make this book a manual for modern school bullies: he does not romanticize crazy actions, he shows how they can end. The book is intended for older readers who want to plunge into their past, or for those who are interested in the life of teenagers of the sixties in a specific historical period of their country. It may also be of interest to teachers who work with “difficult” teenagers.
