“Lucy felt a little frightened, but she felt very inquisitive and excited as well. She looked back over her shoulder and there, between the dark tree-trunks, she could still see the open doorway of the wardrobe and even catch a glimpse of the empty room from which she had set out. (She had, of course, left the door open, for she knew that it is a very silly thing to shut oneself into a wardrobe.) It seemed to be still daylight there. “I can always get back if anything goes wrong,” thought Lucy. She began to walk forward, crunch-crunch over the snow and through the wood towards the other light.
In about ten minutes she reached it and found that it was a lamp-post.”
– C. S. Lewis, from The Lion, The Witch and the Wardrobe
