’I can give you the power to fly to her house,’ the Queen said, ‘but I can’t open the door for you.’
’The window I flew out at will be open,’ Peter said confidently. ‘Mother always keeps it open in the hope that I may fly back.’
’How do you know?’ they asked, quite surprised, and, really, Peter could not explain how he knew.
’I just do know,’ he said.
So as he persisted in his wish, they had to grant it. The way they gave him power to fly was this: They all tickled him on the shoulder, and soon he felt a funny itching in that part, and then up he rose higher and higher, and flew away out of the Gardens and over the housetops.
