MY 8-YEAR-OLD SON GAVE UP HIS LUNCH MONEY TO BUY A LITTLE GIRL WITH DOWN SYNDROME A RED DRESS — THE NEXT MORNING, OUR LAWN WAS COVERED WITH FIFTY LUNCHBOXES.

Neatly banded stacks of it.

To an eight-year-old who had skipped lunch for a month to afford one small dress, it looked like a fortune fallen out of the sky, and his first instinct — bless him — was that something this big had to be a crime.

But it wasn’t stolen.

On top of the money sat a folded letter, soft with handling, addressed in careful handwriting:

“For the boy who gave my granddaughter a red dress.”
