One of the quieter surprises of getting older is realizing that life isn't just a collection of events. It's a collection of seasons.

Most of the time you don't recognize a season while you're living it. It simply feels like life. Saturday mornings driving kids to soccer. The annual beach vacation. Sunday dinners with your parents. The familiar drive between two places you've come to know by heart.

Only later do you realize those weren't isolated experiences. They belonged to a particular arrangement of life — a specific combination of people, places, responsibilities, and routines that made them possible.

Then, one by one, the pieces change.

Children grow up. Parents pass away. A business is sold. A house is no longer home.

And suddenly a route you've traveled for years quietly disappears.

Driving home from New Mexico after visiting Rachel and meeting our newest granddaughter, Shirley said something offhand.

"Next time we do this drive, we should stop at Petrified Forest."

For a second I almost agreed.

Then I realized something.

There probably won't be a next time. Not because we can't drive there. Not because anything bad happened. Because life changed. We sold the house.

For years that drive between California and New Mexico had become familiar. We knew the rhythm of it — where we liked to stop, the stretches that dragged, the landmarks we looked for. And every time we passed the signs for Petrified Forest, we thought: next time.

But the route had quietly disappeared.

The strange part is that this wasn't really about Petrified Forest. We could go tomorrow — book a flight, rent a car, make a trip of it.

But it wouldn't be the same.

Because what I was reacting to wasn't losing access to a place. It was losing access to a season.

That drive belonged to a particular version of life: a daughter in New Mexico, a home in California, parents healthy enough to travel, enough predictability that another visit always felt inevitable.

None of those things ended dramatically. They just changed. And once enough conditions changed, the route disappeared.

I've noticed this pattern in smaller ways too.

There are restaurants I thought I missed. What I actually missed was being younger and eating there with people I don't see much anymore.

There are neighborhoods I thought I wanted to revisit. What I actually wanted was dinner with the friends who no longer live there.

There's a business I occasionally think about. What I actually miss is building something with Shirley — the rhythm of that, the shared problem-solving, the sense of working toward something together.

In each case, what I thought I was attached to was the place.

What I was actually attached to was the season.

This distinction matters. Because if what we really value is the season itself, we might participate more fully while we're still in it.

Stay a little longer. Take the detour. Have the conversation. Not because every moment is precious — that becomes its own kind of pressure — but because ordinary conditions quietly expire. And once they do, recreating the experience rarely recreates the feeling.

Places remain. Seasons don't.

And sometimes what looks like nostalgia is simply gratitude arriving late.
