Three primary school girls and a smaller, younger schoolboy wait to cross from Many Wharf to the Corso. The middle girl leans forward on a post, as if beginning a ritual. The boy stands on tip-toes to whisper in her left ear, and stands back. A dark-haired girl leans in to whisper in her right ear, and she stands back. The boy starts walking, but returns because the lights haven’t changed.

We’ll never know what was said.
