A stranger beside me on a flight asked, “Could you pretend you fell asleep on my shoulder?” I almost said no. I had just left Chicago with my five-year-old daughter, two suitcases, and a marriage that had fallen apart three days earlier. But I agreed. Two hours later, I woke up still leaning against him—and discovered the quiet man beside me was one of the country’s best-known billionaires. Then my phone reconnected, and a message from my ex-husband appeared: I KNOW YOU TOOK FIONA TO NEW YORK.

Fiona considered this.

Apparently he had passed the test.

For the next hour, Luca did something I had almost forgotten men were capable of doing.

He was helpful without making a performance of being helpful.

When Fiona dropped a crayon, he picked it up.

When I struggled to open the tray table while balancing her juice, he held the cup.

When the flight attendant asked whether we needed anything, he waited for me to answer rather than speaking for me.

He did not ask why I was traveling alone.

He did not ask whether I was married.

He did not tell me his life story.

He certainly did not flirt.

That made me trust him more than charm would have.
