Who likes to feel laughed at?

Once upon a time, the world woke up. It was the funniest story that ever happened. And then it could have been the end, everyone slapping their knees, except no one got the joke, so they just kept living. It would take too much time to explain the joke, so everyone is very patient with each other, and humorless. We ruffle each others' hair, and pretend to be grumpy about this small consolation. If you catch someone's eye right after they see a balloon that someone has lost hold of, they will show you a piece of the infinite, blue chuckling music that we are deaf to. But it doesn't make them happy, for who likes to feel laughed at?
