I CAME HOME EARLY FROM A MEETING AND SAW MY EX-WIFE ON TV—WITH FOUR FIVE-YEAR-OLD CHILDREN WHO HAD MY EYES. I HAD LEFT HER BELIEVING SHE COULD NEVER BECOME A MOTHER, WHILE SHE RAISED THEM ALONE.

Leo was the first to become angry. “Why now?”

Elena didn’t hide behind a fairy tale. “Because adults make terrible mistakes, sweetie.”

“Did he make a mistake?”

“Yes. A very big one.”

Their first meeting happened at a public park beside the Charles River. Alex arrived twenty minutes early, bringing only a simple soccer ball after texting Elena to ask whether it was appropriate.

The four children stood in a line, watching him as though he were a substitute teacher.

Maya asked whether he was rich because she had seen a photograph of his office building online.

Lucas wanted to know if he knew how to ride a two-wheel bike.

Clara noticed the dimple on his cheek, reached up, and touched her own.

Leo remained completely silent.

Finally, after the other three ran toward the swings, Leo stayed directly in front of Alex.

“My mom never talked bad about you,” the boy said quietly.
