6 billion && you

There are 6,470,818,671 people in the world.
Some are running scared.
Some are coming home.
Some tell lies to make it through the day.
Others are just now facing the truth.
Some are evil men, at war with good.
&& some are good struggling with evil.
6 billion people in the world,
6 billion souls,
&& sometimes all I need is one.
