Elf on a shelf

Intro Nikola, the Elf on a shelf, sits on the shelf watching you this Christmas season. One day you walk into the living room and noticed there is an Elf on the shelf. You don't remember seeing her there the day before. You didn't put her there. You can feel her eyes following you every time you walk by. You decide to throw her out since you don't know where she came from and because you don't like the feeling of being watched. Later you see her sitting right back on the shelf. Over time you notice that she's in a different position every time you see her. You start to wonder if the stories are true that The Elf on the shelf reports back to Santa if you have been naughty or nice. You try to hide her but she keeps returning to the shelf.
