PLZ HELPRead the passage from The Lion, the Witch, and the Wardrobe.

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.
