Harry's status as orphan gives him a freedom other children can only dream about (guiltily, of course). No child wants to lose their parents, yet the idea of being removed from the expectations of parents is alluring. The orphan in literature is freed from the obligation to satisfy his/her parents, and from the inevitable realization that his/her parents are flawed human beings. There is something liberating, too, about being transported into the kind of surrogate family which boarding school represents, where the relationships are less intense and the boundaries perhaps more clearly defined.
J. K. RowlingI speak now, Harry Potter, directly to you. You have permitted your friends to die for you rather than face me yourself. I shall wait for one hour in the Forbidden Forest. If, at the end of that hour, you have not come to me, have not given yourself up, then battle recommences. This time, I shall enter the fray myself, Harry Potter, and I shall find you, and I shall punish every last man, woman, and child who has tried to conceal you from me. One hour.
J. K. RowlingHe did not know or care whether they were wizards or Muggles, friends or foes; all he cared about was that a dark stain was spreading across Dobby's front, and that he had stretched out his thin arms to Harry with a look of supplication. Harry caught him and laid him sideways on the cool grass. "Dobby, no, don't die, don't die -" The elf's eyes found him, and his lips trembled with the effort to form words. "Harry...Potter..." And then with a little shudder the elf became quite still, and his eyes were nothing more than great glassy orbs, sprinkled with light from the stars they could not see.
