Peter Pan is a tribute to the miracles and wonders of childhood. Childhood as presented in Peter Pan incorporates both sadness and happiness. This is a very important realistic element of Barrie's play. In order for children to appreciate happiness, and to fully experience it, they also need to become acquainted with sadness.

Although a fantasy world where children can escape to, Neverland is not an idealized place. Neverland incorporates both happiness and sadness in the same way that real life does. It is commonly accepted that with the passage of time, memories of childhood become less and less clear. This is what J.M.

The fact that Mrs. Darling – just like any other mother, as Barrie writes – tries to tidy up her children's minds and let only the good things come to surface for children to experience the following day is in fact, her attempt to protect her children from hurt…
