Original title: Старожил

Andrei Krutikov was the first child born in the settlement of the hydroelectric station workers. The residents of the settlement named a street after him. Years passed, and the young city grew. Andrei grew up to be a mischievous, lying, and wild storyteller. But then a new boy, Borya Skalov, appeared in his class. Unintentionally, Andrei started to imitate the serious and responsible Boris, and he didn't even notice how his life began to change.
