What the Jesus Flying Fuckery is up with visual artists who don't care about fashion or decor? Visual artists. You create beautiful things! Why don't you want beauty all around you at every moment? I know you understand colour theory, you have no excuse!

I may also just be a colossal bitch (okay, I am a colossal bitch, whatever) and I should just learn to relax and accept that for some people, being surrounded by tokens of their hobbies and interests is amazingly comforting and makes them feel at home.
Even if their couch is objectively hideous.
