The Little White Bird
The Little White Bird is a British novel by J. M. Barrie, ranging in tone from fantasy and whimsy to social comedy with dark, aggressive undertones. It was published in November 1902, by Hodder & Stoughton in the UK and Scribner's in the US, although the latter had released it serially in the monthly Scribner's Magazine from August to November. The book attained prominence and longevity thanks to several chapters written in a softer tone than the rest of the book, which introduced the character and mythology of Peter Pan. In 1906, those chapters were published separately as a children's book, Peter Pan in Kensington Gardens.The Peter Pan story began as one chapter and grew to an "elaborate book-within-a-book" of more than one hundred pages during the four years Barrie worked on The Little White Bird.The complete book has also been published under the title The Little White Bird, or Adventures in Kensington Gardens.

And if David asks why I decline, I explain that it is because I have no desire to meet the woman.
"Come this time, father," he urged lately, "for it is her birthday, and she is twenty-six," which is so great an age to David, that I think he fears she cannot last much longer.

Context: If you ask your mother whether she knew about Peter Pan when she was a little girl she will say, "Why, of course, I did, child," and if you ask her whether he rode on a goat in those days she will say, "What a foolish question to ask; certainly he did." 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.
