You studied at the university. And you were sitting with your classmate Leon. he wrote down almost nothing and often interfered with everyone. Every lesson, every minute, he rocked on his chair or asked you, "what is this?" "I didn't understand anything, did you?" "why did it happen like this here?" and so on. When he was rocking back in his chair, he fell down. Everyone immediately started laughing, and he was rubbing the back of his head, because he hit his head on another desk. ".. haha," he laughed at himself sadly and through pain.
