Some people,” remarked Mary Poppins, putting her down, “think a great deal too much. Of that I am sure. - P. L. Travers

Mary Poppins is both a joy and a curse to me as a writer ... As a writer, you can feel awfully imprisoned, because people, having had so much of one thing, want you always to go on doing more of the same.

This is the way the wheel turns, coming at last to full circle, with wild as well as tame at he crib; lion and turtle-dove together an barnyard beasts lying down with the fox. For wild and tame are but two hlaves and here, where all begins and ends, everything must be whole.
And always, among the sleepers, there must be somebody waking - somewhere, someone, waking and watchful. Or what would happen to the world..?

Jane and Michael sat at the window watching for Mr. Banks to come home, and listening to the sound of the East Wind blowing through the naked branches of the cherry-trees in the Lane. The trees themselves, turning and bending in the half light, looked as though they had gone mad and were dancing their roots out of the ground. "There he is!" said Michael, pointing suddenly to a shape that banged heavily against the gate. Jane peered through the gathering darkness.
"That's not Daddy," she said. "It's somebody else."
Then the shape, tossed and bent under the wind, lifted the latch of the gate, and they could see that it belonged to a woman, who was holding her hat on with one hand and carrying a bag in the other. As they watched, Jane and Michael saw a curious thing happen. As soon as the shape was inside the gate the wind seemed to catch her up into the air and fling her at the house. It was as though it had flung her first at the gate, waited for her to open it, and then had lifted and thrown her, bag and all, at the front door. The watching children heard a terrific bang, and as she landed the whole house shook.
"How funny! I've never seen that happen before," said Michael.
