Finally, Mother clues readers into why she’s so worried about protecting Luke: she’s afraid the Government will take him from her (and harm him) if they find out he exists. Luke seems to grasp that his life depends on listening to her, and it helps him cope to think that he’s special. But again, note that hiding means that Luke essentially acts like a much younger child: he’s home all day with Mother, rather than making his own friends and living his own life. His life is very circumscribed, even if it's the safest way for him to live.
