I live in a very old city. There are beautiful old houses here still being used. Heck! There are still functioning outhoses here older than the USA.
I just came home from a trip down town, and I see all these beautiful houses being pissed on. They are "tagged" all over. What's the point?
I have seen beutiful murals painted by "free" artists. They do it on abandoned houses, never on any functioning equipment or houses that are still in use.
The scribblers though writes on just about anything they can. That's nothing more than marking your territory, and that makes you nothing more than a dog!
Guess what cultural enriching group of people that allmost exclusively do the tagging?
I'll give you a hint.
They don't like dogs (or pigs) very much.
Don't ever, ever take a dump in your own nest!
