She liked to watch the surprised look on their faces when she touched them.
She got on during the rush hour press. A crowd of humanity surged through the doors and packed themselves into the trains. She picked her target on the platform while waiting and followed him through the doors when the train came to a stop. She liked variety. Sometimes it was a young businessman, gray suit, white shirt with tie, folded newspaper. Sometimes a college student, loaded down with books and stressed to the edge for midterms or finals. Or a hard hat, tired from walking the steel in the skyscrapers, armed with tool belt, coffee thermos and lunch pail.
How did she make her choice? That eludes me still. Did she keep a tally and venture out with a specific target in mind or was it a random choice, a mental flip of the coin? When she had found him though, the light came into her eyes. The hunt was on. She moved through the throng with a skill derived from experience. She arranged to be facing him when the closely pressed crowd settled itself for the ride. Avoiding any greetings, as most train riders, she looked aimlessly around the car as the train moved away from the platform.
