“We should catch up properly” is one of the most common sentences exchanged at a conference, and one of the least reliable. It gets said warmly, meant sincerely, and then both people walk back into their own packed day — a session starting, a colleague waving them over, a phone buzzing — and the promise simply never acquires a time. By the flight home, neither person is quite sure whose job it was to follow up, and the conversation that was supposed to happen never does. At a multi-day event where you and that person are both actually in the same city for forty-eight hours, that overlap is sometimes the only one you’ll get all year.

Why the promise evaporates

The sentence costs nothing to say and commits to nothing in particular, which is exactly why it’s so easy and so unreliable. Neither person wants to be the one who seems overeager by naming a time on the spot, so the natural default is to leave it open — “let’s figure something out” — and open plans made in a hallway rarely survive contact with two separately packed schedules. The hallway conversation itself is real and worth having regardless of what comes after it. The problem isn’t that the exchange was shallow; it’s that goodwill alone doesn’t put anything on a calendar.

Lock it before you separate

The fix is almost embarrassingly simple and almost never done: before you walk off in different directions, pull out your phone, actually look at tomorrow, and name a slot out loud — not “I’ll email you,” but “Thursday, half past eight, by registration.” It doesn’t need a calendar invite or any formality at all; it needs one sentence spoken while you’re both still standing there with nothing else competing for the decision. This is a different tool from a formal meeting-request system arranged ahead of travel — it’s the informal version, usable the moment a hallway conversation makes you want a second one, with nothing to set up in advance.

Swap a number, not just a connection

A LinkedIn connection sent in the moment feels like it accomplishes the same thing and usually doesn’t — platform messages sit unread in a separate app neither of you checks during a packed day, and by the time either one opens it, the conference is over. A phone number is the better trade specifically because conference plans change constantly: a session runs long, a prior meeting overlaps, the agreed spot turns out to be impossible to find in a crowded hall. A text reaches someone in the next five minutes. A LinkedIn message usually reaches them next Tuesday.

If the first slot falls through

It often will — that’s the nature of a day built around other people’s schedules, not yours. The habit that actually works isn’t getting the first slot right; it’s treating a missed one as something to immediately replace rather than quietly let go. A text sent the moment it’s clear the 8:30 isn’t happening — “running long, coffee at 10 instead?” — keeps the plan alive past the one obstacle that would otherwise end it. The promise that actually gets kept is rarely the one made with the most warmth in the hallway; it’s the one that got a specific time, and then got rescued the first time that time stopped working.
