An episode from our show's early days: Stories about what happens when strangers are kind — and when they're not. Prologue: Brett Leveridge was standing on the subway platform when a man walked by, stopping in front of each passenger to deliver a quiet verdict: "You're in. You're out. You can stay. You—gotta go." Most people ignored him. But Brett found himself hoping for the thumbs up.
