A week later, an email from Ryan arrived at Annie’s address: subject line — “Swap Debrief: 24 July.” Inside: three bullet points. He’d started a volunteer rotation to run snacks at the robotics club; he’d learned to say “thank you” the way Annie taught the volunteers to hear it; he’d sewn a missing button on Mateo’s jacket. Annie replied with a photo: their puppet, refurbished and seated atop a volunteer sign-up sheet.
