“All the world is made of faith, and trust, and pixie dust.”

So, when Peter would come and get you, he would always have a little pixie with him right? Well sometimes it's not Tinkerbell, its another pixie; you see, fairies are so small that they don't live for very long. Peter always forgets them when they are gone, it doesn't hurt him you see, to forget. He's a child, sometimes things just don't matter as much as they would for adults.
When he does come, and he very well just might, he has a fairy, and it sprinkles you with pixie dust. I always think that you should always remember the motto, 'Faith, Trust, and Pixie Dust' with that you can fly anywhere you want, but Peter doesn't want to fly just anywhere however, he wants us to fly home with him, to stay forever and ever. Most mothers however just want their children to stay for spring cleaning. Peter started this tradition with Wendy, when Mrs. Darling said she could go help him with spring cleaning, so since then whenever Peter does come, he only takes you for a while, not to say his house is clean, of course not! He's a young lad who sometimes forgets the virtues of cleaning and sorts. When Peter brings you home he say's he'll come back for you next year, but more often then not he will forget about you, and come at sporadic moments in your life. He didn't come much for Wendy, so don't think he'll remember you every year either. He also took Jane, Wendy's little girl, she and her children if I'm not mistaken still go with Peter when he needs them to help clean his home.
What happens though when you, the little child who flew with Peter grows up? What do you think happens to that poor boy who has no one? He forgets, sometimes he remembers the children as they grow up, but more often he'll forget, oh of course he'll be sad when you leave, he doesn't like watching people grow up. Let me remind you however, he was and still is the only little boy who never grew up, despite what all the movies and books may say about Peter, he NEVER grew up. He watched the Lost Boys mature into men and have a family, but he himself never wanted to grow up and become a man, as he put it, "I don't want to go to school and learn solemn things," he told her passionately. "I don't want to be a man. O Wendy's mother, if I was to wake up and feel there was a beard!" - Peter Pan talking to Mrs. Darling 
Peter just couldn't grasp the concept of growing up, and why would he want to? Sure he doesn't have a mother, but he's been on his own for how long? Maybe ten or thirteen years and he is certainly not ready to grow up. Peter doesn't even want to look into the future to see what he could grow up to be, because if he does so then he will forsake childhood and be forced to grow up. 
And we wouldn't the boy who will never grow to grow up now do we?
