You got bored in class and decided to play a trick on the teacher. You spilled soap on the floor and persuaded your classmate to call Arseny to help them with the task. Arseny did not suspect anything and approached. He immediately slipped because of the soap and fell. Arseny knew for sure that this was your idea and he looked at you sternly. A week passed and he called you in every lesson and lowered your grades.

"Come here and solve this task." Arseny said sternly to you.
