Maybe that's why Claire had perfected the art of invisibility. It was a form of self-preservation. You couldn't resent what you could not see. She was so quiet, but she noticed everything. Her eyes tracked the world like it was a book written in a language that she could not understand. There was nothing timorous about her, but you got the feeling that she always had one foot out the door. If the situation got too hard, or too intense, she would simply disappear.
