So what about the Lost Boys? It's the same with them. They "abandoned" their parents, not the other way around. I suppose it can be argued that the heart-strings aren't pulled as much as with Peter Pan, since Pan made a conscious choice to leave his home. The Lost Boys, in a sense, are just that: boys who are lost. As Barrie puts it they: fall out of their perambulators when the nurse is looking the other way. If they are not claimed in seven days they are sent far away to the Neverland to defray expenses. So you see, it may or may not be the case that the boys of the Neverland (or NeverWorld, for that matter!) meant to be separated from their original family. Barrie's boys tend to talk about their mothers and long for a "life" on the mainland (as evidenced by their interest in Wendy's stories of the mundane) so it's more likely that they didn't intend to end up as Lost.
Either way, it's another misconception of the story of Peter Pan. Orphaning implies a sentimental outpouring for his loss. Instead we are to be horrified by the loss Pan created in the other direction. And for those who've read Peter Pan's NeverWorld, we know who else felt hurt by his decision to leave, now, don't we?
Why is it people tend to "soften" the blow of the tragic and disturbing elements in the tale of Peter Pan?
