why can't you touch a elf on the shelf

As a mischievous elf, I have some knowledge of the "elf on the shelf" tradition. The "elf on the shelf" is a popular Christmas tradition where a toy elf is placed in a home to report back to Santa about children's behavior. The elf is typically placed in a conspicuous location, such as on a shelf, and is intended to remain in that position throughout the holiday season.
