Answer: Anna says that Alice has "had quite a life" (after she read Dan's book that was based on Alice). Presumably Alice has been through difficult situations: abuse, neglect, etc. She considers herself a "nobody" and enjoys lying as a form of control. Which is why she never told Dan her real name, or everything about herself. She could never trust anybody completely. She also says "I'm the one who leaves." She prefers to leave men before they can leave her.
