Just an interesting quote to think or discuss from Banksy the graffiti artist from the book "Wall and Piece".....
" Some people become cops because they want to make the world a better place.
Some people become vandals because they want to make the world a better looking place."

I'm no vandal nor am i trying to encourage people to become graffiti artists but is there any harm in adding some colour to some of the grey in this world... Maybe if it happens to be on your wall!?
