“Before Peter Pan belonged to Wendy he belonged to the girl with the crow feather in her hair”

To Sandy Duncan, who had told her "You're the only Peter Pan I'll ever know" in a meeting after a Duncan's performance in the role, as quoted in Mary Martin : Broadway Legend (2008) by Ronald L. Davis. p. 183

Then if you ask your grandmother whether she knew about Peter Pan when she was a girl, she also says, "Why, of course, I did, child," but if you ask her whether he rode on a goat in those days, she says she never heard of his having a goat. Perhaps she has forgotten, just as she sometimes forgets your name and calls you Mildred, which is your mother's name. Still, she could hardly forget such an important thing as the goat. Therefore there was no goat when your grandmother was a little girl. This shows that, in telling the story of Peter Pan, to begin with the goat (as most people do) is as silly as to put on your jacket before your vest.
Of course, it also shows that Peter is ever so old, but he is really always the same age, so that does not matter in the least.
