In the universe, we had a fairly strict teaching in TAU (theory of automatic control).

And here, at one of the practical lessons, he calls another student to solve the task. P-prepod and C-student

P: Ivanov to the board!

C: Maybe not me, I can’t do it.

P: To the board, I said! You will all succeed!

The student is unwilling to stick to the board.

Q: What are you standing for? Remove everything from the board.

In a minute:

P is ster? I said you’ll get it all right, sit down. Petrov to the board!
