Peter Pan embodies the desire of many people to never grow up because he does not age. He magically stays a child forever in a fairy tale land with his friends. Many of us would like to continue the innocent and simplistic life we lead as children. Of course, we all have to grow up sometime. In the story, Peter never grows up. He never gets older or more mature. Wendy, the young girl he leaves Neverland to visit, does age. She grows up and has children of her own. This only highlights the lack of changes in Peter. This character has become so well known for his eternal youth that we even use it in common phrases. Someone who does rash, childish things or avoids responsibilities in an attempt to stay young might be said to have Peter Pan syndrome.
