About this scene
Public bench, weekday afternoon, urban park. She's in a sundress with her legs crossed, headphones in, scrolling her phone. Camera is at distance, hidden, with a long lens. She is unaware. The footage runs nearly three minutes of her unguarded sitting, occasionally shifting position, once tying back her hair, once taking a phone call she ends in under a minute. The wind catches her dress hem twice and she does not adjust it the second time.
What to watch for
The unguarded body language is the point. People posture differently when they know they're seen. She does not posture once. The dress hem moments are the clearest tell because adjusting clothing is so automatic that not doing it means she's not aware of being watched. The phone call is the only break in her routine and after she ends it she goes right back to scrolling. The camera angle holds steady for the full duration without her ever looking up.
