She returned to her 12th birthday bcuz she thinks it was unimportant. While she was reliving this she realized that all humans are blind. She realized that she took life for granted and did not appreciate the little things. She did not appreciate what she had until she had lost it. In the beginning the other dead people had warned her not to return to the land of the living but she still did it. When she returned she told them "I should have listened to you.
