Fight the fighters, not their wars. - Banksy

[Description of a stuffed mouse dressed as a graffiti artist that Banksy snuck into the London Museum as an exhibit:] "The Banksus Militius is a virulent pest that marks its territory with a series of elaborate signs. Professor R Langford of University College of London states, 'Laugh now but one day they may well be in charge'."

Remember crime against property is not real crime. People look at an oil painting and admire the use of brushstrokes to convey meaning. People look at a graffiti painting and admire the use of a drainpipe to gain access.

Pace yourself and repeat [graffitiing] as often as you feel inadequate and no-one listens to a word you say.
