“It was almost noon when the plane touched down at the Triad airport on the outskirts of Greensboro. There was a hire car waiting for me; I waved my notepad at the dashboard to transmit my profile, then waited as the seating and controls rearranged themselves slightly, piezoelectric actuators humming.

I just stood there and watched you walk by. You were so engrossed you didn’t even notice me.” I twisted the loop of her hair around my finger.”
