A pun lands in your own head and you laugh alone in the elevator, no one to share it with and no need to. Born with Mercury in your fifth house, the house of play and the first song hummed for nobody, you think in wordplay, in flirtation, in the doodle crawling up the margin of a meeting agenda. Your mind is sharpest exactly when it has been let off the leash. Spend an hour making nothing useful and see what shows up uninvited. Send the joke. Flirt with the idea, with the blank page, with the person who can keep up. It curdles the day cleverness stops being for fun and starts being how you ask to be loved, because that turns a free gift into a nightly audition, and the laughs get thinner the harder you chase them. Be funny to yourself first, in the kitchen, with the radio on. A mind that delights its own private self does not run dry of charm in public, not for a very long time.
