There is so much noise everywhere in the world today. The sound of voices, cars and trains that I can't remember a time when one could take a walk outside with only the sweet sound of nature as a companion. I wish I could drown out all the racket created by bells, horns, automobiles and people, and the only way to do that is to put on headphones of the noise-cancelling variety. If I decide to hear my favorite song, well, then I see your clamor, and I raise you one with the sound of my choosing.
