On the plane I was not applying my own lesson.
I had labeled the girl disrespectful, her mother impossible, and the next twelve hours ruined.
I hadn't yet considered that a child could behave badly for reasons she didn't understand herself.
In fairness, the first signs offered no reason to imagine anything complicated.
The mother had dismissed a simple request with contempt.
The girl had smiled.
Any passenger in my position would have been irritated.
What troubles me when I remember those minutes is not the irritation.
It is the certainty with which I believed the irritation explained everything.
"I'm asking politely."
"And I'm answering politely."
The girl smiled and kicked again.
I turned forward because I knew how easily anger could make a bad moment worse.
At the hospital, I had watched frightened families say terrible things to people who were trying to help.
I did not assume a rude sentence defined an entire person.
But the kicks became a rhythm, each one arriving just as my body began to relax.
Across the aisle, an elderly passenger lifted his eyes from a paperback.
Before boarding, I had talked to Elena for four minutes beside a vending machine.
She asked about the presentation, and I said it had gone well despite a microphone that failed at the worst possible moment.
She reminded me to drink water and promised the boys would be asleep by the time I crossed the ocean.
I promised to send a message when the aircraft landed.
There was comfort in having a person who cared whether I arrived, and whose questions I could answer without fear.
On the plane, that comfort made me impatient with anyone interfering with the journey home.
I did not yet know that the little girl behind me seemed to be searching for the same reassurance.
I only knew her shoes were striking my chair and that nobody responsible for her seemed interested in stopping it.
The air vent rattled above my head.
I turned its narrow stream toward my face and tried to imagine the silence of our bedroom in Chicago.
Another kick came before I could complete the thought.
I opened my eyes and made the first request that would connect our stories.
"You okay there, Doc?" he whispered after noticing the conference name on my jacket.
"I will be if the seat survives."
He didn't laugh.
"I've watched her do it since boarding."
I pressed the call button and explained the problem to a flight attendant named Maya.
Maya crouched beside the girl's row and asked her to keep her feet down.
The mother finally removed an earbud.
"Are you seriously policing how my daughter sits?"
I had flown through storms, missed connections, and spent entire nights beside patients whose lives depended on my hands.
I thought that experience had made me exceptionally patient.
The next kick challenged that flattering opinion of myself.
I adjusted the cushion, tried to count backward from one hundred, and listened to the engine noise.
The cabin seemed to have room for everybody's exhaustion except mine.
When I looked back again, Sophie's expression was almost blank, as though she were waiting to see whether I would react.
"Only asking that she not strike the seat ahead, ma'am."
"She's uncomfortable."
"We can bring a pillow," Maya offered.
