A block from me, an old ice-skating rink was torn down last summer in preparation for the construction of two new apartment buildings. For some reason, the project seems to be on hold, but as I was driving by the other day, I noticed that the walls of the adjacent businesses - the walls that face the new project - are now covered with that bulbous graffiti that seems to be everywhere in this part of the world. Apparently, there is now a generation of young people who think that they have a perfect right to deface other people’s property.
My old grammar teacher would have to get a new red marker after grading your post!
Graffiti goes back before the current generation.
Just a heads up, private property or not graffiti has been around as long as mankind has existed.
