In life, we should all learn to consider others. It is only when we all learn to put others first that the world will be stripped of greed, selfishness and the likes.
Consider it bad manners, pure selfishness, disregard, and lack of consideration for others to play music through your cell phone’s speaker in a public place or quiet lounge/area.
Please, if you must play your favorite music, stick your ear piece in your ears and enjoy it all the way; most people just want to listen to the sound of the wind not your favorite music. Can you do this?
