context: In the story, Peter Pan, a magical boy who refuses to grow up, brings the Darling children (Wendy, John, and Michael) from London to Neverland, where they have adventures that include a confrontation with the pirate Captain Hook and his crew. Later, the children feel homesick and wish to go home. Wendy invites Peter and the Lost Boys to come with them so they can be adopted. The Lost Boys are eager to do so, but Peter refuses because he does not wish to grow up. Wendy and her brothers and the Lost Boys are captured by the pirates, but rescued by Peter, who forces Captain Hook to walk the plank and be eaten by the crocodile who once ate his hand. Wendy and the boys return to the Darling home, where Mrs. Darling meets Peter for the first time and offers to adopt him, but he refuses for the same reason that he refused to go back with Wendy and the boys - he has no intention of growing up. Peter asks Wendy to return to Neverland with him, and Mrs. Darling agrees to allow Wendy to go back once a year to help Peter with his spring cleaning.
