The catch-up that never happens is a design fault, not a lie

There is a settled way of talking about vague social invitations. It is worth asking how much of it survives contact with the detail.

What the sentence is actually doing

We should catch up sometime is sincere in almost every case, which is why it feels unfair to dismiss it as an empty pleasantry. The problem is structural: it names a desire, assigns the work to nobody in particular and specifies no date, place or next action.

Every ordinary week contains dozens of items that do have dates attached, and those items win by default against one that has none. Both people leave the conversation feeling the matter is in hand, which removes the small discomfort that might otherwise have produced an actual plan. The sentence therefore achieves the opposite of what its speakers intend, discharging the urge to arrange something without arranging anything at all.

Why nobody follows up

Following up means deciding you are the one who wants it more, and that asymmetry feels slightly exposing to most adults. Sending a date also risks a refusal, whereas leaving it vague preserves the comfortable fiction that the meeting is merely pending rather than dead.

Time passes and the follow-up gets harder rather than easier, because any message now carries an implicit reference to the length of the silence. After several months the message would have to acknowledge the gap, and most people would rather send nothing than send an apology. None of this involves anybody deciding they do not want to see the other person, which is what makes the waste so complete.

The version that works

A workable invitation contains a specific activity, a specific date and an unspoken acceptance that the answer might reasonably be no. Two proposed dates outperform an open question, because the recipient is then choosing rather than generating, and generating is the expensive half. Attaching the plan to something already happening, a match, a market, a train you are taking anyway, removes any need to justify the occasion.

Short notice is not rude between adults; a message on Tuesday about Thursday often lands better than a request to look ahead to March. If the answer is no, the useful reply is another date rather than a retreat, since declining a date is rarely declining the person.

Handling the pile of dormant intentions

Most people are carrying a list of fifteen or twenty people they genuinely meant to see and have not seen for years. The pile feels faintly shameful, which keeps it untouched, and untouched piles grow steadily more intimidating with every month that passes over them.

Working through it does not require an apology; it requires one specific proposal per person, sent without any commentary about the silence. Expect a low hit rate, because half of those people are carrying their own pile and will simply never get around to answering.

A quarter of them saying yes is a transformed year, and the ones who never reply have cost you a few minutes of typing.

When the vague version is honest

Sometimes the sentence is a polite way of expressing goodwill without wanting a friendship, and reading that correctly saves everybody a good deal of trouble. The signal is not the words but what happens after a specific proposal, because goodwill without availability shows up as repeated soft refusals. Two declines with no counter-offer is usually enough information, and pressing beyond that converts warmth into awkwardness for both of you.

That is a legitimate outcome rather than a rejection, since adults have finite capacity and are allowed to be fond of people they never see. The real mistake is spending years waiting for a sentence that was never going to turn itself into a date.

Making it a habit rather than an event

Keep each proposal small enough that you can send it without a run-up, because friction at the sending stage is what kills the practice. Three invitations a month is not a personality change; it is roughly four minutes of typing spread across four separate weeks. Track it loosely if your memory is unreliable, since the people you think about most are not necessarily the people you see least.

Accept that some invitations will land in a badly timed week and be declined for reasons that have nothing whatever to do with you. The aim is a steady low rate of proposals rather than one annual burst of good intentions every January.

The takeaway

Replace the sentence with a date, and most of your dormant friendships turn out to have been dormant rather than over.

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