The youngsters filed into the large conference room at the Community Service Society in Manhattan. Each picked up a slice of pizza and a can of soda from a small table that had been set up along one wall, then took a seat at the large table in the center of the room. They were from a public school in the Bronx, about 20 of them, 13 and 14 years old, and they’d agreed to talk to me about their lives.
