THE teenage girl is elegantly dressed in white skirt and heels and carries a large umbrella on her walk through the evening summer heat from Oxford Street, Surry Hills, to Sydney's Central Railway Station.
Under the sandstone railway bridge arch at the intersection of Eddy Avenue and Elizabeth Street, she meets two teenage boys who have stepped off a train wearing baseball caps, jeans and runners. She gives one a peck on the cheek.
Over the next 4½ hours, they roam the streets of the CBD, window shopping, talking and buying the odd soft drink. They are unaware CCTV cameras are recording their every movement.
