Leo’s entire face lit up like a sunrise, and he grabbed my hand and squeezed.

“That’s Dad!” “I know, buddy.”

I pulled out my phone and started recording — Leo’s face, mostly, his shining eyes, because I wanted to capture this for Luca, wanted my husband to see later exactly how much his son adored him, exactly how his boy glowed at the mere sound of his voice over a speaker.

Luca gave the usual welcome: the weather in Chicago, the flight time, one of the painfully corny pilot jokes he loved and delivered with such obvious delight.

Leo was luminous beside me.
