By far the most perceptive and moving review I ever read for Peter Pan appeared, ironically, in the French newspaper Le Figaro, following the Paris production of Peter Pan in 1909 (which was performed in English!). Who ever wrote it surely sensed the hidden kiss...
"That little girl [Wendy] who wanted to live normally, and who nevertheless tried to break through her own limitations – that little girl is our soul. All of us, at one time or another, have seen a dazzling sprite come in at a window that opens to the sky. Were there any among us who did not cry, when we saw him: "I know who you are: you are my happiness!"
If we look deep down in our memories, we will find Peter Pan: he is our fine hopes as we start forth, our certainty that we shall triumph, our complete confidence in ourselves, which for a moment lifted us on high, only to throw us to the ground later on. It was that prodigious hour when destiny hovered above an immense joy, before crushing it. We placed all that we love in life in Peter's hands. He didn’t understand, and went back to fairyland. Peter Pan is what cannot be. He stands for our earliest memories and dreams that do not grow old along with our selves."
(Le Figaro, June 19th, 1909)
