“Quit being so loud when you’re in public. Be respectful of others around you. Don’t talk loudly on your phone or play games with the sound on. Don’t use speakerphone. Don’t play music without earbuds. Don’t blast your music in a vehicle if you are in a residential area. If you want to listen to loud music, invest in headphones.”
