So they compete against each other until graffiti causes someone to go to far. Now we are in an all out war to cause as much pain to the other side as possible. Does the pain and injury intended go beyond the "wrong" believed to have been done? Yep... of course it does. When the other side is an annoyance to you just because they breathe the same air you do.... you got issues.
What will you do? Are you going to go back to the environment, to the people, to the places that have done all they can do to destroy you and your love?
