Jake is not his name. He is across the Tasman, the last message in our thread is eight months old, and I could not tell you what it was about without scrolling back to check. If you had asked me last week whether we were close I would have said yes without pausing, and I would have meant it.
There are forty or sixty people in the same category. Some are down the road, some are in Wellington, some in Melbourne or London. I think about all of them. I talk to them a fraction of that.
Forty or sixty is not a number I picked for effect. It is roughly the layer Robin Dunbar’s group keeps finding wherever there is a record of who people actually contact: an inner five, a sympathy group of about fifteen, and then an affinity layer of around fifty who are genuinely yours without being daily company. (Robin I. M. Dunbar 2016) That is a small, bounded, knowable set. Which is the strange part. I am not failing to keep up with a cast of thousands. I am losing people out of a group of fifty.
Just adult life
The obvious reading is that this is simply what adult life does. People get busy, friends scatter across time zones, nobody can hold forty relationships at full volume, and some drift is the ordinary cost of everyone getting on with it. Or, sterner: this is a discipline problem. Set reminders, make the calls, stop making excuses.
Both are fair. Neither is wrong about the mechanics of a week. But both take the same thing for granted, which is that a friendship going quiet is a friendship that has cooled, and that the cooling is either inevitable or my fault.
What family survives that friendship does not
That reading held until I went looking for what actually happens to a relationship when the contact stops.
Roberts and Dunbar followed 25 people for 18 months through the move from school to university, which is the life event that scatters a network on purpose, and tracked every relationship as the contact fell away. (S. G. B. Roberts and R. I. M. Dunbar 2011) Friendships turned out to be highly sensitive to it. As the frequency of contact and shared activity dropped, the emotional intensity of the friendship dropped with it. Kin relationships, across the same 18 months and the same silences, held steady. Family survived the gap. Friends did not.
The finding I keep returning to is the one underneath that. Feeling psychologically close to an old friend did not protect the friendship. Only communicating or doing things together did. So the thing I would have offered as evidence that Jake and I were fine, that I think about him most weeks, is not weak evidence. It is not evidence of anything. Roberts and Dunbar came back to it in 2015 from the other side and got the same answer: closeness is held up by active maintenance, and left alone it declines. (S. G. B. Roberts and R. I. M. Dunbar 2015)
Why the feeling is no defence
Which exposes the trap, and it is a specific one. Caring is passive. It happens on its own, in your head, unbidden, warm, and completely invisible to the person it is about. Contact is active. It takes a decision, a spare twenty minutes, a call across a time difference. And because caring feels like something, because you really are thinking about Jake, it impersonates staying in touch. You get the internal experience of the friendship being alive while the external fact of it goes silent, and nothing in you flags the difference, because from the inside the caring is doing all the work.
The asymmetry underneath is plain and slightly brutal. Losing touch requires no action whatsoever. It is entropy, and it proceeds by doing nothing at all. Staying in touch is effort pushed against that entropy, forever, and it is endlessly skippable, especially with the scattered ones, where a single call is a whole production of time zones and good moments. Over a long enough run, everybody loses to that.
And the decay is silent, which is what makes it dangerous. Nothing announces it. No signal fires to say you are three weeks from losing Jake, the way a low battery warns you. By the time the gap is visible it is already eight months deep and faintly awkward to cross.
The tools built for this, and the one that died
The software that exists for the problem files itself under a category called personal CRM, which is customer relationship management with the customer taken out, and the name is most of what is wrong with it. It asks you to maintain records: cards, tags, notes, a follow-up date on a human being. That is more work loaded onto the effortful side of an asymmetry that was already losing, which is why people use one twice and never open it again. Disorganisation was never the problem.
Something warmer is not a new idea either, and the honest thing to say is that the best-funded version of it is dead. Path capped how many people you could connect to, citing Dunbar’s work directly, at 50 and later 150, raised around $70 million, and shut down in October 2018 having burned through $66.2 million. (Tech Startups 2018) Intentionally small and beautifully made was not, by itself, a business.
What a prompt cannot manufacture
There is a complication in the research that bothers me more than Path does. A Dutch study that re-interviewed the same people seven years apart found only about half of their network members retained, and the churn ran largely on context: relationships ended as the shared settings that produced them dissolved, not because anyone decided. And Roberts and Dunbar’s follow-up found that maintenance is not one behaviour: closeness was best preserved by talking for the women in the study and by doing things together for the men. (S. G. B. Roberts and R. I. M. Dunbar 2015)
So a prompt closes exactly one gap. It closes the distance between meaning to call and calling. It cannot rebuild the Thursday five-a-side that used to generate the contact without anyone having to intend it. What is left to build is narrow, and the narrowness is the whole of it: make a decay nobody can feel visible before it is eight months deep, then remove the one step that never happens on its own, which is the deciding.
We lose the things that decay silently, not the things that fail loudly. A friendship gives no warning because there is nothing inside it built to warn: no due date, no notice period, no moment at which anyone can be said to have defaulted. Family holds through the silence because the tie does not run on the contact. Friendship is the tie that is made of the contact, which is why it can be full of feeling right up to the week there is nothing left of it.
