A woman with a key ring in her hand is in a powerful position. She stands at the pedestrian crossing, erect, sure of herself. She is willing to wait for the cars and bicycles to pass.
She is not in a hurry. Ready as she is to unlock her car or the door to her house in her own time.
Nor is she going to let anyone in who has no business there.
Her heart is her own.
(So trespassers will be . . . .)
