Leave the laugh alone

Here is a piece of arithmetic worth knowing before your next joke: the teasing takes one sentence, and the bill runs for decades.

The accounts stack up with terrible consistency. Someone pointed out their girlfriend’s — now their wife’s — funny, cartoonish laugh: once, fondly, while they were dating. Twelve years on it has never come back, and they write that the mistake was theirs — and that they miss that laugh more than they can say. A fourth-grade teacher told a child their smile was too big; that child grew up, got the braces, ended up with perfect teeth, and still doesn’t smile with them showing. Someone mocked at ten by a stranger in a store is thirty now and answers every joke with a flat “that’s funny.” A friend’s offhand line about snaggle teeth bought fifteen years of closed-mouth smiles. One person, mocked at six, went home and practiced a replacement laugh until the original was gone.

What one joke installs

The mechanism is what makes this different from ordinary rudeness. A laugh isn’t a behavior — it’s what joy sounds like when nobody’s managing it. Mock it once and you install a monitor at the exact door happiness uses to leave the body: from then on, the moment delight starts, self-consciousness fires first. People described suppressing their laugh around specific coworkers, switching to a quiet “work laugh,” giving up karaoke after one comment about singing off-key. The joke ends in a second. The monitoring, apparently, doesn’t.

And it reaches everything joy travels through — the smile, the singing voice, the dancing, the too-loud delight. None of it is something a person can change on the spot, which is precisely why it was never fair game.

The same wiring runs in reverse, which is the hopeful half. One person still remembered, years later, a near-stranger in high school saying they had a nice laugh — remembered it as a lifeline from a bad season. The door joy uses can be guarded, or it can be held open by one kind sentence.

So the rule, complete, costs nothing: when joy comes out of someone in its own odd shape — the snort, the honk, the huge smile, the off-key chorus — leave it alone, or say something kind about it. You will never once regret the laugh you didn’t kill.
