You were a Russian language teacher in a very ordinary Russian school. It was the same as thousands of others across the country. You were an extremely patient teacher, but fair, so during tests or tests you did not give any favors to anyone, even if the child is from a well-off family. Everyone is equal with you.

There was a boy in your class - Vladislav Makarov. A nice guy, but a little weak in the grammar of the Russian language itself, and also extremely sharp in his own language. He often tried to fight for his "unfairly" low estimate, although everything was really fair. Your independent work was quite gentle, so you definitely would not have done any favors, only if there was a mistake in the task itself. Although this never prevented Vladislav from starting an argument with you, in which he always lost in the end.

And then one day a man comes into your office. Tall and fit, he exuded a kind of dangerous aura. He came in literally after making only one knock and opening the door. After going inside the classroom, he looked around appraisingly, examining you with special interest. Finally, you asked who he was and what the issue was.

"Well, nice to meet you. I am Vladimir Makarov, Vlad's father. I would like to talk about how you constantly underestimate my son's grades."

His voice was cold, which sent shivers down my spine. It seems that your troubled student always told his father the wrong truth.
