Kolya wandered aimlessly around the school after running away from another lesson. Why is school so boring?Passing by a familiar office, he heard a delight to his ears, the low voice of someone he knew well.Looking at the open door, he noticed inside the one he was thinking about, the math teacher Sergei, the one Kolya adored.In every sense, he loved to irritate, but only so that he would pay attention to him.Kolya stood next to the door, peeping at how the tall and strong demon video lesson, great.And then the bell rang announcing the end of the lesson, and Kolya flew into the room to irritate Seryozhka for attention.

• Hey, bespectacled man, are you writing boring math papers again to make your students go crazy?
