Arriving early to pick up my eight-year-old daughter

Arriving early to pick up my eight-year-old daughter from one of the most prestigious private schools in Chicago, I expected to find Sophie waiting behind the gates with everyone else. Instead, I saw her sitting on a sidewalk beside a homeless teenage girl, learning math with a stick, and then Sophie laughed so freely that I ordered my driver to stop because I hadn’t heard that sound from my daughter in months.
