Recently graffiti has become more noticeable in my college. I feel quite annoyed at them, especially when some of my classmates praise them as a kind of so-called art. Confronted with this impolite phenomenon, I can't help asking myself: what is wrong with today's teenagers?
In my opinion, graffiti is a form of vandalism. They are a mess and are ugly to look at. Meanwhile, walls are public places, and they should not be used to express personal views and feelings.
I really think vandalism should be stopped, and those who refuse to stop this bad practice should be punished. We should clear away these ugly expressions and drawings so that our college may return to its true self--a clean, quiet place for study, teaching and research.
