Barrie's Peter Pan is a blend of marvelous and disturbing strangeness. First of all, it is the kind dog of the family who is the "nurse" of the children while their parents go out to dinner. And after many adventures with Lily the Tiger, the jealous Tinker Bell and the evil Hook, Peter brings the three children home. On their return, the parents find the whole crew and adopt the lost children. Peter promises to come back to see Wendy every year and take her for a walk to Neverland. But he forgets, and when he comes back, Wendy's an adult and a mother. Peter then takes his daughter Jane with him. Then, when Jane is too old, he takes her daughter, Margaret.
And Barrie notes that this cycle will continue forever.
