Two teenage boys sit together on the bus. One has his head tipped back and a bucket hat over his eyes.

A man approaches the vacant seat in front of them, but stops.

“Tommy your bag!” says the second boy, and the first boy jerks awake. He stares. He leaps up and reaches forward, dragging a backpack from the seat in front and onto his lap. He wraps his arms around it and drops his head on top of it.

The man sits down.
