We’re used to the typical “Not Allowed” signs in ordinary life: no rollerblading, “no shirt, no shoes, no service,” no dogs allowed, etc. They’re usually obvious, but it makes you realize that the signs wouldn’t exist unless some bozo went into a nice restaurant barefoot, or that a dog pooped on a children’s playground. The signs are the very definition of cause and effect. So it makes us wonder: What had to happen for someone to to erect these signs? The world is a strange place.
