Some women treat attention like a spilled drink. A glance happens, then there is a nervous laugh, then a report to the friend beside them, then a whole investigation of who looked and why.
She stops making it a scene.
If someone notices her at the bar, she lets it pass. Maybe she smiles. Maybe she keeps walking. Maybe she keeps talking to her friend and reaches for the door like nothing happened. That calm does half the work. She is not begging to be seen, but she is not flinching from it either.
