people that go around claiming to have OCD are usually the messiest people out, they might line up the peas on their plate but the rest of their house is like a laundry bomb
rarely, almost never
i think the rest of the world definitely does
if it was figurative, a mural, or a witty political statement . . . tags and swear words in isolation do not seem artistic to me
i would probably be more likely to assume that she is extra scared of it because of some incident that has happened in her past
that would be a cool option, i would be interested in that one
