Once, the word was a whisper carved into a cave wall by a man who saw lightning and wanted to marry it. He did not know grammar, but he knew: ****. It is the sound a soul makes when it remembers it left the stove on in a past life. It is a sneeze of truth, a hiccup of the cosmos, a four-letter eclipse of reason and restraint. “****,” says the poet, when words betray him. “****,” says the scientist, when atoms refuse to behave. It is the punctuation of panic, the jazz note in an otherwise silent scream, the laugh-track of God. It means everything when you don’t mean anything, and it means nothing when you feel everything. It is both the crime and the confession. The knock, the door, the absence of door. So how do you write it? You don’t. You exhale it through clenched teeth as you fall in love with a mistake. You etch it into the back of a napkin after three whiskeys and a revelation. You scream it into a pillow until the pillow understands. Then you kiss it. And never speak of it again.
