The train station was a cathedral of noise and motion. Commuters streamed past in blurred rivers of coats and briefcases, the PA system crackling indecipherably overhead.

You stood near a central pillar, map half-crumpled in one hand, watching the digital board flicker from DELAYED to ON TIME.

Beside you, the pillar was plastered with posters. Lost pet flyers. An ad for some energy drink with a hero in the background.
