You're typing vandalism to make it seem like I also support breaking stuff or something? I have no problem with living in a building with stuff scribbled on it, and it sounds cool to have a customized building by the neighbours. Imagine all the kids that live in the building leave their name somewhere, it'd add to the history. Right now my building is white, and has bright orange metal bars. Is white with orange bars better? I don't know, it's just what it is and I didn't decide it either. I really don't see scribbles as counting as vandalism. I know it counts by law, but I don't have to agree to the law I just have to follow it, and out of all the laws that can be broken, it's one that never lost me any sleep when I see people doing it.
My university for example, in every single room, every single table is scribbled on and marked for years and years. When I arrived there as a fresh faced student I saw scribbles that were 30 years old. Some people left their names, some people said they didn't like professor X, some people left Maxwell's equations on there. I'm so glad the university didn't consider it vandalism. This could be applied to so many more things. It had zero negative impact on my education or experience in the classroom, so how can it be considered vandalism?
