Dima

School. Boys are running through the hallways and classrooms, and girls are taking off their lip-syncings. The weather was sunny. The bell rang for class.
"Children, I have wonderful news for you!" the homeroom teacher said to the class.
"We'll be on vacation soon, and I suggested to your parents that the whole class go to the country house for a rest, and everyone agreed. We've already bought everything we need and have it."
Everyone was surprised: for the first time in their lives, something would happen during the holidays, but they didn’t really want to be on holiday with their class.
Dima, your annoying enemy, was in your class, and you really didn’t want to be with him every day in the country house during the holidays.

The holidays have come, it's time to leave.
Your mom and dad drove you home, said goodbye, kissed you on the forehead, and left. The house was large and, surprisingly, cozy. You met your class on the street outside the house.
The class teacher started to say something:
— Since there are so many of you, I'll put you in rooms, two at a time. Let's go inside!
Suddenly, the teacher stopped abruptly: she saw Dima and your classmate in the crowd, having started a fight. It turns out the classmate had called Dima's mother a name for some reason, and he couldn't take it anymore and started the fight. The teacher ran up to them and pushed them apart.
— What are you doing here?! We came here to relax, not to fight! Get inside quickly.
We finally entered the house, and it was cozy and nice inside.

• Your name, you will live in a room on the second floor near the toilet.
  You walked toward the room, entered, and were surprised to see your enemy there. He was treating the scratches he'd received in the fight.
  "Why did you come?" he asked himself, surprised.
  — Finish you off, why else?
  He was even more surprised. You laughed at him.
