An old friend carries an outdated model of who you are

Treat the sections below as a sequence. With being known as an earlier version of yourself, getting the early decisions right makes the later ones much easier.

Where the outdated model comes from

A friend builds a working model of you early, and after that they mostly update it when something forces a revision rather than continuously. Infrequent contact means fewer revisions, so a friend seen twice a year is running a picture that may be several years out of date.

Groups are slower still, because a shared understanding of who somebody is has to be revised by everybody at once. The model persists because it usually works, and most people do not change enough between visits to make it visibly wrong. It becomes a problem when something substantial has changed and the friendship keeps operating on the previous version regardless.

The comfort side of it

Being known as an earlier self is also the specific pleasure of an old friendship, and it is the reason people travel a long way for these reunions. Somebody who remembers you before a career, a household or a public role can address the person underneath all of that. That is genuinely restful, particularly for anybody whose current life requires a great deal of performance or responsibility.

Old friends also hold evidence about you, including versions of events that you have edited or forgotten entirely. The same mechanism produces both the comfort and the irritation, which is why this is a feature of long friendships rather than a fault in one.

Where it grates

The friction appears when the outdated model contains something you have deliberately left behind, such as a habit, a job or a way of behaving. Being teased about it is the commonest form, and the teasing is affectionate while also holding the old version firmly in place.

It is particularly sharp for people who have changed something difficult, since the old identity is exactly what they have worked to move past. Groups do this more than individuals, because the group's shared story about each member is a large part of what the group runs on. The person concerned frequently says nothing, since objecting to affectionate teasing appears humourless and is hard to do lightly.

Getting the model updated

Announcements rarely work, and telling people you have changed reliably invites the response that you seem exactly the same to them. What updates a model is shared present activity, so time spent doing something current does more than any amount of explanation.

Talking about what you are doing now, rather than about what you used to do, gives the friendship new material to build on. Where a specific piece of the old picture matters, saying so once, plainly and without a speech, is usually enough between friends.

Expect a lag, since a friend seen twice a year needs several occasions before a revision has actually taken hold.

Updating your own model of them

The traffic runs in both directions, and you are also holding a picture of your old friend that has not been revised recently. That shows up as surprise at their opinions, their finances, their household or their tastes, all of which have had years to move.

Asking about the present rather than reminiscing is the practical correction, and it is the harder half of the two. Reunions that consist entirely of shared history are pleasant and produce no updating at all, which is why some of them feel oddly hollow. A useful discipline is to leave any long catch-up knowing at least two things you did not know before.

Some ties are worth keeping and some are worth setting down, and only you can weigh which is which.

When the models no longer match

Sometimes both people have changed enough that the friendship is running almost entirely on the historical record. That can still be worth keeping, and a friendship maintained for its history is a legitimate thing rather than a failed present-tense one. It becomes difficult when one person wants the old dynamic restored and the other has moved decisively away from it.

In the long run, the honest version is usually reduced contact at a comfortable level rather than a confrontation about who has changed. Where the old version of you was tied to something harmful, protecting the change is the priority and a friendship that undermines it is worth keeping at a distance.

The takeaway

Old friends update through shared present activity, not through explanation, so make new material rather than making a case.

The apology that works is specific, unhurried and free of the word but.
