The rapprochement with his granddaughter Nastya is going slowly but surely. The girl tells Maria Pavlovna that the numbers in an ordinary magazine no longer frighten anyone — you need to put deuces online. In addition, the annoying curator of the school is trying to convince the mathematician that every bad grade must be supplemented with a good one. Maria Pavlovna sees this as nonsense, and her daughter Natalia sees it as a chance to quickly expel her mother from school.

If parents donate money for curtains, then what do teachers donate for? The answer is simple: you need to give gifts to your birthday colleagues. Natalia is shaking her authority, so she decides to collect two thousand instead of one. To do this, however, you will have to feel like a real collector. Maria Pavlovna also has an unusual idea. After learning that Nastya likes her classmate Bogdan, she tries to arrange for them to go to a stand-up.
