I have long suspected that small talk is not really about talking at all. I mean, obviously it’s about talking, but it’s not about imparting information or saying anything of actual interest.
It is, I think, more accurately described as a kind of human protocol negotiation. A lightweight exchange whose purpose is not to transfer meaningful information, but to confirm that both parties are present, functional, and broadly willing to proceed without causing a scene.
In computer networking terms, it feels rather a lot like a TCP three-way handshake.
That may sound like an over-complicated way to describe “Morning” and “Busy day?” but I maintain it is exactly the right amount of over-complication.
The analogy works on several levels at once.
| TCP handshake | Human small talk |
|---|---|
| SYN | “Morning.” |
| SYN/ACK | “Morning. Busy today?” |
| ACK | “Yeah, not too bad.” |
| Connection established | Actual conversation may now proceed |
The actual content is almost irrelevant.
The handshake exists to establish availability, willingness, compatibility, safety, and communication parameters. Small talk does much the same thing. It is not there to win prizes for insight. It is there to say, in the safest possible way:
I see you. You seem non-threatening. We may now continue.
That is quite a useful invention, really.
It is also, for some of us, faintly bewildering.
Because my brain has a tendency to assume conversations should do one of three things:
- exchange useful information.
- explore an interesting idea.
- contain at least one genuinely terrible joke.
Small talk often does none of these things.
Which is not to say it is pointless. Far from it. It is just that its point is not always the same as the point my brain is looking for.
That can make it feel a bit like packet loss.
Some of the signal gets through. Some of it doesn’t. A few words arrive intact, but the important meaning seems to have been dropped somewhere between the intention and the execution.
The weather is discussed.
The weekend is mentioned.
A vague inquiry is made about one’s wellbeing.
And yet the actual data being transmitted is something like:
I am safe. You are safe. We may continue this interaction without immediate risk of social collapse.
That is a rather elegant system when it works properly.
It is also a system with some spectacular failure modes.
Failed Handshake
Sometimes the handshake fails immediately.
You offer the smallest possible opening.
“Morning.”
And the other person replies:
“Is it? I mean the way the world’s going it might as well be the end of days. The planet’s going to hell in a hand basket and we’re all doomed.”
At that point the connection has not merely failed. It has been forcibly terminated, the cable has been unplugged, and the router has probably started smoking.
Connection reset by peer.
Timeout
Then there is the timeout problem.
Someone asks:
“How are you?”
and the answer requires a socially acceptable level of detail, emotional calibration, and acceptable honesty.
My brain, meanwhile, is attempting to calculate whether “fine” is technically accurate, whether “surviving” sounds too bleak, whether “not bad” is too British to be believable (see below!), and whether any response longer than six words will prompt a follow-up I do not have the energy to sustain.
By the time I have finished this internal analysis, the moment has passed.
Connection timed out.
Packet Flooding
Some people go in the opposite direction.
You offer:
“Morning.”
And they respond:
“Morning! Did you see that interesting show on TV last night about medieval bridge taxation? Made me think about my current view on plug in solar panels, my advancing years, my neighbour’s cat, and the collapse of the world’s democratic politics systems..”
That is not a handshake.
That is packet flooding.
ADHD can do this rather beautifully. One tiny conversational spark and suddenly a completely unrelated archive of information is bursting out of the firewall at speed.
Which, to be fair, can sometimes be entertaining.
It just isn’t small talk anymore. There’s nothing small about it.
Encrypted Traffic
Us British people add another layer of complexity, because many of us speak in what is essentially encrypted traffic.
“Not bad.”
Not only is this British understatement at its very best, this can mean:
- life is actually pretty good actually!
- life is acceptable.
- life is mildly annoying and could be better.
- life is a bit of a struggle but let us not make a fuss.
- a bottomless abyss has opened beneath me, but the kettle still works, so we are continuing cup in hand and trying our best to avoid the hordes of demons spewing forth from this hellish portal.
That is an extraordinary amount of information to pack into two words.
It is also one of the reasons small talk can be so difficult to decode. The literal words are only half the message. Tone, timing, context, and cultural expectation carry the rest.
The protocol is not just words.
It is inference, and unfortunately, not something I’m particularly good at.
UDP People
Then there are people who skip the handshake entirely.
They are the conversational equivalent of UDP.
“HELLO STRANGER HERE IS MY INFODUMP OF TRAUMAS, PROBLEMS AND CONCERNS!!.”
No connection setup.
No reliability guarantees.
No orderly exchange of packets.
Just pure, immediate data transfer with absolutely no regard for conventional protocol.
This can be alarming, but occasionally refreshing.
Stateful Firewall
Autistic masking probably deserves its own category here.
It can feel a bit like trying to pass through a stateful firewall while manually monitoring every tiny aspect of your own behaviour.
Eye contact? Adjusted.
Tone? Checked.
Facial expression? Calibrated.
Volume? Sensible.
Response time? Natural enough to avoid suspicion.
Internal panic? Well hidden, hopefully.
The result is not always elegant, but it is functional.. barely.
NAT Traversal
Trying to socialise at parties is also very much like NAT traversal.
You know there is a connection somewhere in there.
You know the other person is a perfectly ordinary human being.
You know you are supposed to be able to reach them.
And yet the routing is somehow wrong, the ports are blocked, and everyone is standing in awkward little clusters pretending not to notice that all communication has become mysteriously more difficult than it should be.
And when you do get into a cluster, the least said about the actual handshaking the better. (Especially Dave with the sweaty palms!)
So Why Does Small Talk Exist At All?
Because it is doing a job.
A very human job.
Small talk reduces uncertainty.
It establishes connection.
It signals intent.
It gives both parties a safe place to stand before deciding whether to move into more meaningful territory.
It is a social compatibility check.
A “yes, we can talk” exchange.
A way of saying:
I am friendly.
You are safe.
We may proceed.
That is actually rather beautiful, when you think about it.
Even if the words themselves are often about absolutely nothing of consequence.
Why It Feels So Hard
For many neurodivergent people, the difficulty is not that small talk is meaningless.
The difficulty is that its meaning is often indirect.
It is a social ritual disguised as conversation.
A lot of the work is happening in the subtext.
And subtext is a slippery little creature.
If your brain prefers clarity, precision, and explicit information, small talk can feel like being asked to decode a message written in invisible ink.
Which, admittedly, is not very helpful.
The Human Side of the Protocol
And yet…
And yet, for all my cantankerous grumbling, I do think there is something lovely about it.
We are, after all, social animals operating a remarkably fragile but surprisingly effective communication system. Small talk is one of the tiny pieces of software that keeps the whole thing from crashing immediately.
It is how we ease into each other’s company.
It is how we test for warmth.
It is how we say, with minimal risk and maximum politeness, that we are willing to share a moment. You’re lowering your shields and allowing the Klingons to beam aboard.
That is not nothing.
In Closing
So yes, perhaps small talk is the human equivalent of a TCP handshake.
A few neat little exchanges whose real purpose is not the content, but the connection.
Sometimes it works perfectly.
Sometimes it fails immediately.
Sometimes the packets arrive out of order.
Sometimes somebody starts talking about medieval bridge taxation or python programming before the connection is even established.
But when it does work, it lets two strangers become, very briefly, not strangers at all.
And really, that is quite a clever trick for a few essentially meaningless words and a friendly look over a cup of coffee.
