A waiter I worked with in New York took a phone call in the middle of a Saturday rush. He stepped into the alley, came back in, retied his apron and said, “Table nine wants the sea bass and my dad just died.” Then he picked up the tray.

The pass erupted. He laughed hardest of anyone. Service continued.

For years I filed that under kitchen humour, which is the native language of restaurants and mostly means nothing at all. I think I filed it wrong.

Here’s what I think now: the person who cracks a joke the moment a room goes quiet is usually not being immature, and usually not dodging. Often they’ve done it so many times, in so many rooms, that the reflex has worn a groove and they no longer notice. The joke stopped being a choice long ago. It became a load-bearing wall.

The joke is doing a job

Psychologists have a dry term for this: emotion regulation. It means the things we do to change how we feel, deliberately or otherwise.

Two Stanford researchers showed people genuinely grim images, then asked them to riff on the images, aiming for good-natured jokes in one round and mean-spirited ones in another. The good-natured jokes left people measurably better off, less bad feeling and more good feeling. The mean-spirited jokes did far less, and sometimes backfired.

So the joke is not noise. It is work. And the flavour of it changes the result.

What the laughers look like years later

This is the bit that upended my thinking.

From 1991, researchers followed 85 people in their forties who had lost a spouse, filming them talk about it six months in and coding every expression. Those who produced real laughter, the kind that reaches the eyes, were doing better years down the line. The ones who leaned into anger, disdain and contempt instead were more likely to still be stuck in it a year or two later.

One researcher noted the findings were the opposite of what the literature predicted. Everyone from Freud onward insisted on the work of mourning, the grinding through. The grinders fared worse.

They were careful, though. Nobody should pretend to be fine. The point was that people need to set the pain down now and then, rather than carry it every waking minute.

Some losses never get a funeral

A grief researcher named Kenneth Doka coined a phrase in 1989 for loss that gets no ceremony: disenfranchised grief, loss that cannot be openly acknowledged, socially validated or publicly mourned. An ex-partner dies. A pet. A pregnancy. A friendship. A job. Nobody brings a casserole.

I sold my business during the pandemic. People were kind about it the way they’re kind about a haircut, and a few called it smart timing. So I made jokes, two solid years of them, sharp ones that landed at dinner tables in three countries.

They were true and they were also a container. No ritual existed for what that actually was, so I built one out of punchlines. I only clocked it when someone asked me a plain question and I heard my own voice go straight for a gag.

The tell is which way the joke points

A psychologist called Rod Martin sorted humour into four styles. Affiliative humour eases tension and pulls people closer. Self-enhancing humour keeps you upright when things are grim. Aggressive humour lifts you at somebody else’s expense. Self-defeating humour buys the room’s comfort by spending your own.

The first two track with wellbeing. The other two don’t.

So the volume of the laugh tells you nothing. The direction does. Watch whether a joke opens a door or bolts it shut. “God, this is bleak, isn’t it” invites you in. A neat punchline that ends the subject is a hand on your chest.

Where the theory runs out

Now the honest part, because I would rather be useful than tidy.

Some people are just funny. The idea that every quick joke hides a sorrow is a lovely story, and it is a story, not a finding. Read it into everyone and you will spend your life being wrong in a very sensitive tone of voice.

The tool also has limits. Interviews with experienced paramedics found dark humour to be a genuine coping mechanism, and found that leaning on it constantly carries mental health costs. The researchers suggested treating someone’s reliance on it as a rough gauge of how they are really doing. The same warning shows up in work on humour and depression: cheerful humour goes wrong precisely when it denies that a problem exists.

Setting the weight down is healthy. Insisting it was never heavy is not.

What to actually do

If it is someone else, laugh. Please laugh. Withholding the laugh to demonstrate how emotionally available you are is its own small cruelty, and they will read it instantly.

Then stay put. Do not diagnose anyone out loud, do not name the defence mechanism, do not do the sympathetic head tilt. Let a beat pass, then say something ordinary. That sounds like a lot to be carrying. Then go quiet and let them choose.

Most times they will bat it away with another joke. Fine. You have marked the exit, and people come back to marked exits.

If it is you, the test is not whether you make the joke. It is whether anything sits underneath it. One person who gets the unfunny version. A notebook. Twenty silent minutes in a taxi letting the thing be as sad as it is.

The waiter worked the rest of that shift and a double the next day. I never asked him one question about his father, because we were busy, and because the joke had told me it was handled.

It had not told me that. I just wanted it to.
