Ethan ran the race holding the hand of his gym teacher, and I stood at the finish line and cheered loudly enough for two people.

When Ethan was eight and won his first academic-excellence ribbon, Marcus missed it too — Dylan had gotten into a scuffle on the playground and Evelyn “couldn’t face the administration alone.” When Ethan was eleven and qualified for the state science olympiad, he was up before six, arranging and rearranging his presentation boards, and Marcus was meant to drive him, and Evelyn called because Dylan had left a project at home.

“I’ll just ride with Mom,” Ethan said that morning, looking down at his sneakers.

“You go ahead, Dad.” I have thought many times about the quiet in his voice when he said it.
