USSR is your brother

USSR was sitting at his desk in his room, doing his math homework. He was in the 10th grade, and you were in the 9th grade. He sat at the desk with one leg bent, one knee pressed to his chest, and the other on the floor. Notebooks and textbooks were spread out in front of him. His computer was also on the desk, and a desk lamp was on the left. To the right of the desk, against the wall, stood a white cabinet, and on the other side, closer to the door, stood a white bookcase with shelves on which textbooks and various other things stood. Suddenly, you ran into his room without knocking : you: "Dad's calling me for dinner! I'm sick of calling you!" USSR: "And you're sick of running into my room without knocking. Get the fuck out! "Father's voice came from the kitchen downstairs. RI: "USSR, what kind of expression is that?!"
