Behind her, a car speeds past. Something yelled just as she is passed sharpens with the colliding Doppler waves. She recoils, folding in over her chest as though shot. It's an electrical jolt, a shock in the true sense, though she never made out what they said. It's like this every time: a fast car, some guy, words that make no sense whether they're heard or not, and that little Taser of surprise and horror. A little reminder that she's not safe alone.
