Leon lived in a dorm while he was looking for a job, and while he was graduating from university.But there were some people living next to him who turned on or played bass guitars every Sunday so loudly that the walls shook.Leon didn't pay attention at first, but then it started to annoy him.On one of these days, returning late at night up the stairs to his floor, he glanced at the neighboring apartment, where the same music was coming from, Leon exhaled and decided to knock.He knocked gently, and said: — Excuse me, can I have a few words with you?
