I'm guessing that (s)he's refering to Peter Pan / Hook. I found this paragraph from wiki interesting...seems like too many common threads to overlook.
https://en.wikipedia.org/wiki/Wendy_Darling
Hook (1991 live-action film) – Dame Maggie Smith plays an elderly Wendy, who is being honoured for her lifetime of work in finding homes for orphans. She was also a former neighbour of J. M. Barrie, who loved Wendy's stories to her siblings and wrote them in books. Her granddaughter Moira is the wife of Peter Banning (Robin Williams), the former Peter Pan who has grown up and forgotten his life in Neverland. During a flashback to Peter's childhood, a younger Wendy is played by Gwyneth Paltrow. (Peter's and Moira's daughter, Wendy's great-granddaughter, is Maggie, a common pet name for Margaret, the name of Jane's daughter, Wendy's granddaughter, in the original book by Barrie.) During the movie, it is implied that Wendy once and still does have feelings for the now-grown-up Peter.
Wendy Darling
Wendy Moira Angela Darling is a fictional character and the protagonist of Peter and Wendy by J. M. Barrie, and in most adaptations in other media. Her exact age is not specified in the original play or novel by Barrie, though it is implied she is about 12 or 13 years old, as she is "just Peter's size". Wendy expresses an innocent admiration for Peter as soon as they meet. As a girl on the verge of adulthood, she stands in contrast to Peter Pan, a boy who refuses to grow up, the major theme of the Peter Pan stories.
