Sora提示词：A realistic vertical 9:16 vid

A realistic vertical 9:16 video, first-person POV, action camera.
Cold winter morning, breath visible in the air.

An older American man in his early 70s unlocks a small coffee shop door.
He wears a winter coat with a U.S. flag patch and a veteran hat.

The camera wearer asks:
“Did you serve in the military?”

The man replies quietly:
“Yeah. That was years ago. This is my routine now.”

Natural sound only.
