Once upon a time, there lived two brothers — Foma and Yerema. But around the neighborhood, everyone called them by their nicknames: Nedodel (Undone) and Peredel (Overdone), because each of them had a particular trait. Foma, whenever he started a task, would abandon it before even managing to put any effort into it. As for his brother Yerema, it was the complete opposite — no matter what task he took on, he would always overdo it. One day, the two "craftsmen" decided to go and learn some common sense.
