The last summer evening you're already missing

Do you remember the exact moment you realized the evening had turned?

Not when it was over. Before that. When the light went amber and you thought, without meaning to: this is almost gone. The air still warm, the voices still close, and yet something in you was already reaching back, trying to hold what hadn't left yet. It comes when you sense that a beautiful moment is about to become part of the past.

Was that grief? Or was it something quieter. A kind of attention the body pays when it knows something counts?

The present research provides support for the counterintuitive hypothesis that thinking about an experience's ending can enhance one's present enjoyment of it.— Jaime L. Kurtz, Psychological Science, 2008[6]

Because here is what the researchers found: thinking about an ending, really letting yourself feel that it's ending , makes the experience more vivid, not less. You lean in, you listen harder, you stay a little longer than you planned. So when you sat on that balcony in late August and felt the strange pull of missing something you were still inside, were you ruining the evening? Or were you the only one at the table who was truly, fully there?

And when did you last have an evening like that?

One specific evening. The kind where the conversation went somewhere you didn't expect, where nobody checked their phone for a long stretch, where you said something true and the other person didn't flinch. How long ago was that? Weeks? The spring before last?

Constantine Sedikides and Tim Wildschut, psychologists at the University of Southampton who have spent years mapping the interior life of nostalgia, found that nearly 80% of the people they studied experienced it at least once a week. And that its content was almost never a place or a thing. It was always, almost without exception, another person.

It is a bittersweet memory that can also give us the strength to act. As those same researchers have noted, nostalgia strengthens our sense of connection with others. It can therefore become an impulse to move forward.

Nostalgia is a psychological resource that protects and fosters mental health.— Zhou, Sedikides, Wildschut & Gao, Psychological Science, 2008[5]

Longing doesn’t necessarily mean that something is missing. It can remind us that that person and that time mattered to us, that they were real. And that we can experience them again. So what does it mean that the face that comes to mind — right now, reading this — is the face of someone you haven't called in a while?

Is it possible that the ache at summer's end isn't about summer at all?

There's a particular Sunday evening, somewhere between late August and early September, when the dark comes an hour earlier than it did a month ago and you stand at the window not quite knowing what to do with yourself. Psychologists call moments like this "end temporal landmarks" — the places where time visibly folds, where one chapter becomes another. Research published in Behavioral Sciences in 2024 found that these moments sharpen one thing in particular: the need to belong. And temporal landmarks — the end of summer, the start of a month — are exactly when we tend to act on it: to reach out, to close a distance that's been quietly growing.

Why does that need feel so urgent on an August evening and so easy to defer on a Tuesday in March?

And if you know — if you've always known — which relationships give your life its actual weight, why is it so hard to protect the time for them?

A strong sense of how fleeting a moment is can be more than melancholy. It can be a good compass, pointing us toward whom to call, whom to text, whom to meet. Toward the people we want to share the passing of time with.

Jeffrey Hall, a communication researcher at the University of Kansas, spent years tracking how adult friendships actually form and hold. His findings, published in the Journal of Social and Personal Relationships in 2019, name something most people feel but rarely say aloud: a close friendship takes around 200 hours together to build. Ordinary evenings, unremarkable in themselves, that pile up until someone truly knows you.

How many of those hours did you spend this summer?

And how many did you mean to spend, and didn't?

Fewer contextual changes in life are known to cause the passage of time to be perceived as faster.— Marc Wittmann & Sandrine Mella, Timing & Time Perception, 2021[10]

Here is the quiet thing about adult life: it doesn’t refuse you those evenings. The calendar just fills before you decide. You keep meaning to call, and keep putting it off — and then August is over, you’re standing at the window, and what you miss is the version of yourself who was there, present with the people you love.

A feeling like this is a signpost. It tells you, plainly, what matters to you — and who.

The researchers who study anticipatory nostalgia — the specific ache of missing something while you're still in it — see it as a signal of value. You only grieve what mattered, and the longing itself is the proof.

So when you feel it, that catch in the chest on the last warm evening, the reluctance to go inside, the wish that the light would hold — what is it pointing toward?

Not toward the summer that’s ending.

Toward a person — toward a conversation you’ve been meaning to have, and a date you’ve been meaning to set.

The evening isn't over yet.

Who are you thinking about right now?
