What the Sea Gives Back: Sea Glass, Rising Water, and the Shape of Love

Attachment Issues

Today, I am in the Outer Banks looking for sea glass.

This is an occupation requiring very little intelligence but a surprising amount of attention.

You walk slowly at the waterline, looking down.

Brown glass is pretty common. Green is better. Blue can produce an excitement wildly disproportionate to the monetary value of the glass in question.

The best pieces are cloudy and smooth.

They did not begin that way.

A newly broken bottle is sharp, transparent, dangerous.

Only after years in the water does glass acquire the softness we prize: rolled through sand, thrown against shells and stone, buried, uncovered, carried offshore, returned again.

The frosting on its surface is damage accumulated exquisitely slowly.

Its rounded edges are evidence of collision.

What we pick up and call beautiful is glass altered by what happened to it.

I find myself thinking about this because the Outer Banks are changing beneath my feet.

The ocean works incrementally.

A few feet here. A dune there. A storm opens an inlet.

Another closes one. Sand migrates. Houses that once stood comfortably back from the water find themselves looking directly into the Atlantic.

Sea level is rising, but barrier islands have always moved. Their instability is not a defect in the system.

It is the system.

We are the ones who find this difficult.

We arrive with surveyors.

We draw property lines across sand.

We build houses.

We name streets.

We take out thirty-year mortgages.

There is something touching about this.

We behave as though the earth has agreed to hold still because we have become attached to it.

It has not.

The Original Shoreline

We do something similar when we fall in love.

We meet someone at a particular moment in their life and begin, almost immediately, to preserve them.

This is who you are.
This is who I am with you.
This is how we touch.
This is what you need from me.

We call this knowing someone.

Sometimes it is.

Sometimes it is simply remembering them accurately.

There is a difference.

The life partner we marry is already disappearing.

So are we.

Not tragically. Not necessarily.

But continuously.

The woman who wanted children becomes the woman exhausted by them, then the woman who cannot imagine the house without them, then the woman standing in the bedroom of a grown child wondering when exactly the room became a museum.

The ambitious young man becomes successful and discovers that success did not answer the question he thought he was asking.

Bodies alter.

Parents die.

Friends disappear.

Sex changes.

Certain ambitions begin to look ridiculous.

Other desires become impossible not to hear.

Then one morning you look across the kitchen and understand that the person drinking coffee there is not precisely the person you married.

This can feel like betrayal.

It may actually be just the passage of time.

The Marriage to a Ghost

One of the loneliest things that can happen in a long relationship is to remain deeply loved by someone who no longer sees you.

They only see the earlier shoreline.

They know your habits. They can order for you in a restaurant. They remember what you wore on your first date. They know which story you will tell when certain friends come over.

They know you extraordinarily well.

And somehow they have stopped discovering you.

Familiarity can masquerade as attention.

We say, I know you.

Perhaps after thirty years the more loving sentence is:

I know I don't entirely know you anymore.

Tell me.

There is humility in that sentence.

There is also fear.

Because if I permit you to change, I lose the version of you whose contours I memorized.

And perhaps some certainty about myself.

Husband. Wife. Protector. Desired one. Responsible one. Difficult one. Successful one. Fragile one.

If you cease being who I thought you were, I may have to also reconsider who I have been beside you.

We think we are arguing about behavior.

Sometimes we are plaintively pleading:

Please remain the person around whom I built my life.

The Houses at the Waterline

There are houses along the Outer Banks that were not built at the water's edge.

The water came to them.

A staircase descends into surf.

Pilings stand exposed.

A deck hangs over water.

Inside remain the ordinary structures of domestic life.

A kitchen.

A bedroom.

A porch.

All the little structures with which human beings say:

Here.

This place.

This will be ours.

The sea has no quarrel with any of it.

That may be the most unsettling part.

There is no cruelty in the water.

It is simply moving.

Time is like that too.

We speak of marriages being tested by catastrophe: infidelity, illness, bankruptcy, death.

But many marriages are tested by something quieter, and more relentless.

Time passes.

Two life partners become different people.

And nobody has done anything wrong.

Moving the Lighthouse

At Cape Hatteras, the lighthouse once stood much farther from the ocean than it eventually did.

The lighthouse had not moved.

The shoreline had.

Eventually there was only one sensible response.

They moved the lighthouse.

Not because the lighthouse had failed.

The relationship between the structure and the landscape had changed.

Couples can spend years trying to move the ocean.

Love me the way you used to.

Want what you used to want.

Come back.

Be the woman I married.

Be the man I remember.

But there may be no going back because there is nowhere to go back to.

That coastline no longer exists.

Sometimes the lighthouse has to move.

Not the light.

The lighthouse.

What Time Does to Glass

Sea glass is made by repetition.

Sand. Water. Stone. Collision.

A piece disappears beneath the sand for years.

A storm uncovers it. The sea takes it again. The manufactured gloss disappears. Sharp corners surrender by fractions.

There is no craftsman.

No plan.

Just repeated contact with the world.

We tend to imagine enduring love as preservation.

Perhaps we have it backward.

Perhaps enduring love is partly abrasion.

Not cruelty.

Contact.

The daily experience of having another human being rub against our preferred version of reality.

You discover that your interpretation is not the only interpretation.

That being hurt does not automatically make you right.

That loving someone does not entitle you to possess their interior life.

That an apology costs considerably less than righteousness.

That some truths need saying and others merely want the pleasure of being said.

These discoveries rarely arrive as revelations.

They arrive as abrasion.

Breakfast.

Bills.

Sex.

Children.

Silence.

Disappointment.

A hand reaching across a bed after an argument neither person remembers winning.

Again.

A little less sharp.

If we are lucky.

Because time does not soften everyone.

Some glass simply breaks again.

The Terrible Bargain

There is a bargain hidden inside intimacy that nobody explains when we are young.

To love another person deeply is to become attached to something you cannot keep.

Not because they will necessarily leave you.

Because they will change.

And if you remain together long enough, you will watch it happen.

You will watch the young face become an old one.

You will notice a hand becoming thinner.

You will discover that certain things you once did together have quietly happened for the last time.

You usually will not know which time was the last.

There was a last time you carried your sleeping child upstairs.

A last time your father called.

A last time you and your spouse made love in a particular house.

A last Christmas when everyone was still alive.

Ordinary life conceals these endings from us.

It would probably be unbearable otherwise.

We understand them only afterward.

The shoreline moved during the night.

What Intimacy Asks

When we are young, commitment sounds like the difficult promise.

I will stay.

Later, intimacy asks something harder.

Can you stay while allowing me to become someone you did not anticipate?

And then it asks the same question in return.

Who are you now?

What has the water taken?

What has it uncovered?

What are you frightened of losing?

What have I failed to notice because I preferred the old map?

The task is not to know another person permanently.

Nobody can.

The task is to keep recognizing them.

The Life Partners Who Become Like Sea Glass

After a while I find a piece.

Green.

Small enough to disappear in my palm.

Its edges are completely smooth.

Once it was part of something larger. It had a purpose, a recognizable shape. Somebody may have held it before I did.

Then it broke.

And after the breaking came years.

The sea did not heal the glass.

That is too sentimental.

It altered it.

Every movement took something almost immeasurably small away.

The edge that could once cut skin became round.

The transparent surface became opaque.

Its original shape became unrecoverable.

The glass survived, but not by remaining unchanged.

There are life partners who have lived together for forty or fifty years who sometimes have this quality.

Something worn smooth.

They have discovered how little is accomplished by humiliating the partner with whom one intends to eat breakfast tomorrow.

They know where the sharp places are and, on good days, do not press them.

They have seen each other sick and frightened.

They have watched parents pass and children leave.

They have been disappointing.

They have been disappointed.

And gradually, almost invisibly, some unnecessary hardness has been taken from them.

Not all of it.

Enough.

We imagine the achievement of old love is duration.

Fifty years.

Sixty years.

But duration is merely elapsed time.

The more interesting question is:

What did the time do to them?
Did it make them harder?
Or did all that contact with another imperfect human being slowly alter the surface?

The Last Shoreline

There is one fact about lifelong intimacy we mostly leave out of wedding ceremonies.

If the marriage lasts long enough, it eventually succeeds its way into grief.

One person will almost certainly leave first.

And the other will know something about the marriage that the first never will.

What it was like to be the one left remembering it.

A side of the bed stays empty.

A phrase nobody else says quite correctly.

Perhaps the memory of an old argument becomes precious simply because your life partner is no longer available to continue it.

We spend decades learning another human being knowing full well, that somewhere beneath all our busyness, our knowledge cannot save them.

Nor us.

Love does not defeat impermanence.

It makes impermanence matter.

The Waterline

The tide is coming in.

I walk for a while and look back.

The beach has changed.

Perhaps this is how a life together passes.

A hand no longer reaching automatically across the bed.

Then reaching again.

A silence that once meant anger becoming companionable.

A face becoming familiar in an entirely new way.

One partner slowing down.

The other waiting.

We spend the first part of love trying to close the distance between us.

Perhaps the later work is learning to stand at the moving boundary between two lives without demanding that either one stop changing.

The shoreline is not where the land defeats the sea.

Nor where the sea defeats the land.

It is where they continue to meet.

I put the green glass in my pocket.

Its beauty is not that the ocean returned it unchanged.

The ocean couldn't.

After the breaking, the burial, the collisions, and the long invisible work of water and sand, something remained that could still catch the light.

We cannot keep the life partners we love as they were.

We cannot keep ourselves.

We cannot keep the shoreline.

But we can choose to become gentler with what time changes.
