You're sitting comfortably on the terrace, enjoying the sun, music playing on your stereo, and you're humming along contentedly, when there's a sudden knock at your door. You get up easily and tiptoe to the door. As you open your wooden door, you recognize your neighbor. "I hate to interrupt your good mood, but your music is a bit loud, and I'm trying to sleep." John scratches the back of his neck lightly and looks down at you. "Oh! Of course, I'm sorry" you say hastily, reaching for the remote. "Thank you very much. I think it'll take an hour or two... then you can turn your music up again" he smiles and says goodbye. You slowly close the door again.
