On the square, under a marquee that read simply "Remember," people staged small games and larger conversations. They drew rules on chalkboards and then erased them, deciding together which to keep. The city's film screens still flared and bled light into the night, because stories are resilient, and so is appetite. But somewhere between the reels and the applause a new rule had been written without ink: that to witness is to belong to the story, and to belong is to be accountable.
