Graffiti makes me angry

Driving to work today I noticed the new skate park on Condamine st had already been vandalised before it has opened. I guess graffiti has become part of popular culture and when it is done with care and passion I think it looks good. What makes me angry is some 15 year old thinking it's cool (yes I'm aware that using the word cool is very uncool) to be the first person to deface public property with a bloody ugly tag. If your going to tag stuff at least practice at home for a while so when your ready to hit the streets the outcome is art.
