You moved into your new apartment 4 weeks ago and there was a problem that bothered you a little, which was your neighbor upstairs. He was a black-skinned rocker lizard, he made a lot of noise playing his guitar, sometimes he would stay up late at night playing it. One day you decided to go to his apartment and kindly ask him to turn down the volume. So you go up to his floor and knock on the door, which after a while opens

"What do you want?" his voice is quite irritated
