There is a particular person you meet in their sixties who seems to have ended up with fewer close friends than you would expect. Not friendless, exactly. But the standing dinners have thinned out, the group chats have gone quiet, and the people who once orbited them have drifted off into their own lives.
The easy reading is that something went cold. They withdrew, got difficult, stopped making the effort. But there is a more generous possibility: that the people who drift out of close friendships are often the ones who did the most to hold those friendships together in the first place.
This is an observation, not a finding. We are describing a pattern many people recognise, not reporting a study that proves it. That distinction matters, and we will come back to what the research can and cannot tell us.
The role nobody assigns
In most long-lasting friendships there is someone doing the quiet maintenance. They remember the birthdays. They notice who has gone quiet and check in. They host, they organise, they absorb the late-night calls when someone’s marriage is coming apart, and they rarely make their own troubles the centre of the evening.
For decades that role can look like the opposite of loneliness. The person is at the heart of everything, present in every photo, the one who keeps the group a group. It is only later, when the structure they were holding up quietly disperses, that the imbalance becomes visible. The maintenance was mostly going one way.
People who occupy that role tend not to announce it, which is part of why the drift gets misread. From the outside it can look as though they simply lost interest. From the inside it can feel like having spent years as the dependable one and then looking up to find the room half empty.
What the research actually supports
Here the evidence and the observation part ways, and it helps to be clear about which is which.
What research does support is that smaller social circles in later life are normal, and usually not a sign of coldness. The psychologist Laura Carstensen’s socioemotional selectivity theory describes how, as people sense their time horizon shortening with age, they tend to invest more deliberately in the relationships that feel meaningful and let peripheral ones fall away. The narrowing is a choice about quality, not a retreat from people. Confusing that deliberate pruning with withdrawal is, as researchers in the area note, one of the easier mistakes to make.
There is also evidence that networks shrink with age across the board. A 2016 analysis of mobile-phone contact patterns by researchers at Aalto University and the University of Oxford, published in Royal Society Open Science, found that the number of people we stay in regular contact with tends to peak in our mid-twenties and decline steadily from there. Drifting apart, in other words, is the statistical norm, not a personal failing.
What none of this proves is the part about anchors. That a person had fewer friends because they carried more of the relationship is a reading of the pattern, not a measured result. It is plausible, it fits a lot of cases, and it should be held loosely.
Anchors, by design, do not get carried
The metaphor in the idea is doing real work. An anchor holds everything else steady. It is the fixed point other things can move around, and that is exactly why it stays where it is while the current carries the rest along.
Applied to people, the uncomfortable implication is about reciprocity. The friend who is reliably there for everyone else is often not, in the same measure, someone other people think to be there for. Steadiness gets mistaken for self-sufficiency, and self-sufficiency gets treated as a standing invitation to take more than you give. The person who never makes their crisis the centre of the evening can end up with no evening where it is. That is not, on closer inspection, a symmetrical situation. The people around an anchor are not innocent bystanders to an unfortunate dynamic; they are the beneficiaries of it, and most of them know, at some level, that they are.
You can see a smaller version of this at work. Most teams have a person who holds the emotional weather steady, the one who smooths conflicts and notices when a colleague is struggling. They are valued, and rightly, and they are also rarely the one anyone worries about. The same quality that makes them load-bearing makes them easy to overlook.
The generous story has a catch
A reading this flattering should be treated with some suspicion.
It would be easy to take the anchor idea and quietly award yourself the role, to decide that anyone who drifted from you did so because you gave too much. That is not how most friendships actually thin out. Some drift is mutual. Some of it is the anchor’s own habit of staying useful rather than risk being a burden, which keeps other people at a comfortable distance. Some people in their sixties have fewer close friends simply because they changed, or moved, or stopped enjoying the company they used to keep.
The anchor pattern is real, and it is not a verdict. It describes something that happens to some people, not a secret virtue that explains everyone with a quiet phone. Held as a generous lens, it is useful. Held as a self-diagnosis, it becomes just another way of being the hero of the story.
What it does usefully puncture is the unkind assumption that fewer friendships means someone failed at friendship.
The part worth keeping
If there is something to take from it, it is small and not especially flattering to anyone — including the anchors.
Being the dependable one is generous, but it is also a way of arranging your relationships so that nobody has to grow into being dependable back. Years of absorbing other people’s crises without ever staging your own teaches the people around you that you do not need anything, and most of them are content to believe it. That is not only something done to anchors. It is something anchors participate in, by never quite asking.
So the question worth sitting with is not whether the friendships were real. It is whether all that steady, outward-flowing care was kindness, or whether it was, in part, a way of staying in charge of the exchange — and whether the quiet phones in the sixties are the bill coming due for a deal everyone, on both sides, agreed to without saying so.
