About this scene
Home goods aisle, late afternoon, sparse shopper crowd. She's an Asian woman in her forties, in business casual, browsing kitchenware. The flash happens at her three o'clock. She turns her head, smiles, nods once, and turns back to the shelf. She continues browsing the same shelf for another full minute, picking up products, putting them back, examining items she has clearly already decided about. She does not leave the aisle.
What to watch for
The nod is the small, deliberate detail. It's not big enough to be acknowledgment. It's just enough to be a gesture. Most reactions don't include a nod. Hers does. Watch the products she handles afterward. They get the same level of attention each one received before the flash. She is not pretending to shop. She is actually shopping. The flash happens and she just keeps going at her original pace, with the smile lingering for about thirty seconds longer than it should have.
