A playground at dusk, photographed at a child's eye level. One swing in a row of four is caught mid-arc, slightly motion-blurred, its chains angled forward. The other three hang still. Nobody is in the frame. The sand beneath the moving swing shows fresh scuffs, and a single small shoe print points toward the edge of the photo. Streetlights are just turning on, and the sky is a fading orange-violet.
(Q) Who was just here, and why did they leave before the swing stopped?
