Your shopping is already on the belt and you are now waiting and wondering if the person ahead of you has finished paying. Your day is asking you to finish this task, and this small delay is beginning to feel personal.

The person at the card reader is searching for something: checking their pockets more than once, looking in their buggy, on the floor, on the counter. The cashier waits. You feel that familiar little tightening: surely we could all be getting on with this.

Then the glasses turn up on top of their head. They look around, catch your eye, and laugh. “Well, that’s useful.”

You laugh too, because you recognize the moment. You have spent enough of your own life looking for something you were already carrying. For a few seconds, the person holding up the line becomes someone you can meet.

Your afternoon is still waiting. So is theirs. Yet something in the space between you has changed. I am interested in that change. It is so ordinary that we might scarcely give it a thought, but I suspect it has something to tell us about the life we share.

Before the laugh, you knew this person through their effect on your plans. They were a delay. Nothing especially sinister in that; attention can become very narrow when we are tired or preoccupied. We have all managed to turn another human being into an inconvenience without formally applying for the position of villain.

But their brief, unguarded amusement lets something else through. There is a person here, living a day from the inside, just as you are. You still know almost nothing about them. You have simply stopped needing their whole existence to fit the part they were playing in your afternoon.

There is an intimacy in this recognition. It can arrive between people who will never learn each other’s names. We might call it connection, although that word sometimes makes it sound as if we have built something that was entirely absent a moment before. Perhaps, in some encounters, we become available to something we had ceased to notice. We are already here together.

That sounds almost too obvious to bother writing down. Of course we are. There is the checkout line, with its assortment of people and shopping. But we can occupy the same space while living as though everyone else belongs to the scenery. Recognition changes the place another person has in our attention. Their experience begins to matter, even when it does nothing to advance our plans.

This is where I would like to begin a conversation about unity. The word can become rather grand rather quickly. Give it a few minutes and someone may have us dissolving into the universe before we have managed to pack the groceries. I would prefer to stay beside the card reader a little longer.

“We are all one” is a phrase I have heard offered with great warmth. I understand the longing within it. There is relief in the possibility that the separation we feel is not the whole story. Yet the phrase can also move past the person in front of us. We can be so eager to affirm our shared being that we fail to hear what is particular about their life.

The person ahead of you has a history you do not know. Their laughter may come easily today, or it may be the first easy thing in a difficult morning. That remains theirs. A moment of recognition does not give you access to it, and it does not require them to explain themselves.

Surely a sense of unity can be spacious enough for that. There is something we recognize in another person’s being alive, even while their experience remains beyond our reach. Each of us encounters life from within. We can describe an afternoon to one another, but we cannot hand over the actual feeling of living it. Still, across that distance, a laugh can reach us. Someone’s embarrassment can soften our impatience. We discover that another person’s experience has a place in our own.

The larger questions about consciousness remain open, too. A small laugh would struggle to carry all that philosophical luggage. The encounter itself, though, offers us something to attend to. The separation seemed complete while the stranger was merely in the way. A moment later, it felt less complete. Their presence had acquired a depth our impatience had overlooked.

Perhaps shared life becomes easier to recognize when we loosen our insistence that our own experience is the center of everything happening.

I say that with some affection for the center. It is a busy place. There is usually a great deal to manage there, and occasionally quite a convincing argument that everyone else could improve matters by moving a little faster. We need no additional shame about being human. We might, however, become curious about what our urgency leaves out.

Much of ordinary life encourages us to assess people through what they make possible for us. In a checkout line, speed is useful. The cashier has work to do, and everyone waiting has somewhere to be. The trouble begins when being useful becomes the measure of a person’s place in the world. The one who slows things down can disappear behind the delay.

For a moment, the laughter interrupts that disappearance. Nothing monumental follows. You do not necessarily become friends. You might be impatient again before you reach the car. Recognition can be brief and still matter. It gives us an experience we can return to: another life becoming present to us where, a moment earlier, we had seen only an obstacle.

To me, this offers a modest beginning for a larger inquiry. We can notice what happens when the people around us become real to us again and we can leave space for what we do not know about them. Whatever language we eventually choose for shared being, it ought to be able to live in that space.

The person ahead of you puts their glasses on and finishes paying. They gather their shopping and, as they leave, they catch your eye once more, and the smile between you is easy. Now it is your turn.
