How do we know that the signs with the Braille writing next to the elevators and bathrooms are actually saying what they're supposed to say? Who knows, maybe there's some guy making Braille signs whose greatest joy in life is to screw with the minds of as many blind people as he can. What if the signs are really saying something like, "you're about to piss in the elevator again," or "uh, are you really sure this is the ladies room?" Who knows? Maybe they don't mean anything at all. I've never seen a blind person read one of them. They just seem like a bunch of dots to me. In fact, I don't think I even know any blind people. What's up with that? Pretty suspicious.
