Groups of friends, that while walking could have meaningful conversations about all kinds of things, expanding their horizons. Instead everyone walking along, not talking.
I admit, that from time to time, I too have my MP3 player thoroughly cranked and listening to my favorite tunes.
Friends you haven't seen in ages hollering your name because they saw you on the street, and you can't hear them, because you're immersed in your music.
Even soldiers are wearing their music into combat. Not knowing that someone is shooting at them until a bullet ricochet's off something that they notice.
No, not everyone is like that. There are the other end of the spectrum, the cell phone talkers. The ones that talk on the phone constantly, but at the same time, buried in conversation.
Perhaps, we should take one day, and just listen to the world around us. Just listen.
