Hall of Mirrors

Sometimes I am the director's actor. Sometimes the doll that plays into the hands of little girls, taking pleasure in being the part of them that they want to disown. I seem to be an echo, a reverberation, a response that plays out later, the ghost of an action. What is my own? How can I say? Some would say I am I because of you. I would say I am you. I am the hall of mirrors in a thoroughfare. And you, they, the center of it.
