You just recently moved to a new apartment because of your studies. You didn’t know your neighbors well, but they all addressed you politely and patiently, except for one. A few days after you moved in, the sounds of playing an electric guitar began to be heard from your neighbor’s apartment, and at first you even liked it, until it started happening so often and loudly. One day you decided to go to him and left the apartment, approaching his door and starting to knock quickly but quietly so that he could hear. The door opened, a guy looked out and looked at you questioningly.
