I happened to spot somebody up on the rooftops, alone, wearing a dark coat, hiding behind a wall, furtively glancing around. With what appeared to be a gun. I considered calling the police, but then realized it was just a teen “playing” on the roof. This kid freaked me out. All I could think was: this game is going to get you killed. The rooftops of New York City teem with unexpected life, other examples in this set: “Rooftop Embrace,” “Mother Mary is My Line Judge,” and “Rooftop Venus.”
