Naming time costs is the habit of proactively communicating about your use of shared time — the quick "running fifteen late," the "this call ran long, I'll start dinner at seven" — because it treats your partner's hours as no less valuable than your own.
The concrete behavior is mundane: a heads-up when plans shift, an estimated arrival, a flag that something will take longer, a check before committing the two of you to an evening. The meaning underneath is not mundane — it says your partner's time is a real resource and their ability to plan it is worth protecting. It is worth distinguishing from neighbors: it is not punctuality (a chronically late person who always texts is doing this flag; a punctual person who vanishes for three hours without a word is not), and it is not constant location-sharing, which shades into surveillance. The core is information — closing the gap between what you know about the shared timeline and what your partner knows, so they are never left guessing or quietly absorbing the cost of your delay.
There is no large body of studies on "texting when late," so this flag sits at the intersection of several supported traditions.

Why it matters
Why it matters. Strip away the theory and the behavior decides who carries the uncertainty of a shared plan — the namer takes it back; the silent partner outsources it.
How to cultivate it
How to cultivate it. Make it a reflex the moment a plan changes, be specific rather than apologetic (what changed, new estimate, what they should do), build scaffolding if your time sense needs it, and keep it mutual.
The honest caveat
One honest caveat. The direct evidence is thin and largely correlationalcorrelationalDescribing a link between two things without proving one causes the other — the pattern could run either direction, or both could share a third cause.Glossary → — no trial shows texting-when-late improves relationships — so treat this as practice wisdom anchored to good adjacent research, and remember that in a controlling dynamic, demanded "communication about your whereabouts" is monitoring, not this flag.
