Everyone keeps a friendship ledger and nobody admits to it

What follows is the working version of reciprocity between friends: the decisions in the order you actually meet them, with the reasoning attached.

The accounting nobody declares

Ask directly and most people will say friendship is not about keeping score, and most of them will also be able to tell you who last initiated contact. The tracking is largely automatic, running quietly in the background and only becoming conscious when the balance tips far enough to sting. It counts messages sent, invitations issued, favours done, listening hours logged and occasions attended, in a rough and unwritten way.

Because the ledger is never spoken about, both people can be running very different sets of figures without ever discovering it. Denying that the ledger exists is what makes it dangerous, since an unexamined tally is the one that turns into resentment.

Why exact equality is the wrong target

Two friends rarely have the same capacity at the same time, because illness, small children, demanding jobs and caring duties all consume the surplus that friendship runs on. A friendship insisting on symmetry each month will break during the first period when one person has nothing left to give. The more workable standard is proportionality: each person contributing something close to what they can currently manage, which may be very different amounts.

Over a decade these things tend to even out, and the friendships that survive are usually the ones that tolerated long periods of imbalance. The exception is a friendship where one person has never given anything at any point, which is a different situation entirely.

What contribution actually consists of

Effort is often counted only as initiation, which unfairly ignores the person who always says yes, always shows up and never cancels. Somebody who cannot host may still be the one who remembers the difficult anniversary, drives to the airport or answers the phone at eleven at night. Emotional labour, remembering the details of somebody's life and asking about them later, is real work that leaves no visible trace.

Friendships get into trouble when one person values only the contribution they happen to be good at and discounts the rest. Widening your definition of contribution is often enough to resolve an imbalance that was mostly a measurement error.

When the imbalance is real

A genuinely one-sided friendship has a recognisable pattern: you initiate, they accept, they never initiate, and this persists across years and circumstances. The tell is not the ratio in any given month but the absence of any period in which the direction reversed. Before concluding anything, consider whether the other person has ever been asked, since many people simply follow rather than lead and would happily do more.

Between old friends, asking directly is uncomfortable but efficient: name what you would like more of, once, without producing a list of historical grievances.

The response tells you whether you are dealing with an unreflective friend or an unavailable one, and those need different decisions.

Deciding what to do with the answer

Ending a friendship is not the only option, and it is usually not the best one for a relationship that is pleasant but lopsided. Reducing your own effort to a level you do not resent is often the honest middle path, and many friendships settle comfortably there.

Some friendships are worth subsidising indefinitely, because of history, because of what the person is going through, or simply because you want to. The subsidy only works if you have chosen it consciously, since resentment comes from unchosen giving rather than from giving itself. Revisit the decision occasionally, because circumstances change and a friendship that could not reciprocate in one decade may be the one carrying you in the next.

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

Saying it without a row

Raise it early, when the imbalance is mildly annoying, because a ledger presented after five years arrives as an indictment. Speak about what you want rather than what they failed to do, since the first invites a change and the second invites a defence. Be specific and small: ask them to suggest something once in a while rather than to become a different kind of friend.

The unglamorous truth is that expect them to be surprised, because the person receiving more attention very often has not noticed the pattern at all. Give it a few months before drawing conclusions, as habits of initiation change slowly even when the intention is genuine.

The takeaway

The ledger is not the problem; the problem is running one for years without ever letting the other person see it.

Friendship is largely turning up, repeatedly, when there is no occasion for it.
