In the inky pre-dawn Next Mexico morning, my brother and I head back to the Santa Fe airport. He’s done this thing that somehow never hit my consciousness — rented a car like an Air BNB — which has been incredibly helpful. The sunrise spreads over the horizon, more golden than pink, while the three of us stand talking in the parking lot for just a moment. My brother hands over the keys, and then that’s done. The car’s owner leaves.

My brother and I have time. We can walk through the one-room Santa Fe airport in about three minutes — maybe six, including security. A half moon hangs above us. We kick around words for the phases of the moon, and he teases me, again, about what he claims is my overuse of the word gibbous in my first novel. As the wide Santa Fe sky morphs from black to blue, Orion fades.

On the short flight to Denver, my brother and I are separated by a few rows, each of us peering out the window at the Jemez mountains. We’re back in that enormous flow of airline travel, so many people going so many places, all that fuel and pollution eating up the planet. Not very long ago, people remained on the earth. But for these moments, suspended thousands of miles above the planet, I glimpse my brother and I as separate people but indelibly part of this great human stream, traveling to visit our old parents. Around us, everyone moves through their lives and stories.

The pilot ferries us above the mountains and through the clouds. As I walk into the airport, I say thank you, and I mean it.
