Tinker Bell had understood, but once people got used to the idea of flying, it became easier and they were willing to try it more and more. It wasn't something anyone could get used to over night, especially with things that normally didn't fly, however Nana, the housemaid dog seemed to have enjoyed her brief moment flying. At least she seemed to in Tinks opinion.
Tinker Bell fluttered into the sky once more, flitting around Christine almost lazily, nodding in response to Christine's question about being able to stop. It was that, or start losing your happy thought. That was a bad way to do it, however as you were liable to drop right put of the sky.
She would be willing to allow Christine all of the time she wanted to enjoy flying, though it was an experience that she could have again, whenever she wanted. All he had to do was ask. Flying was so useful for many things, and it was easier to get places when you flew. That's how she and Peter and the Darlings got to and from Neverland.
