You Can Move the Elf

We were driving home from seeing Mary Poppins when the brunette twin started asking about the Elf on the Shelf. We've had an elf for a couple of years now.
This year the girls saw it for sale at Target. They started asking about it, but I deflected the questions. I just didn't feel like dealing with it at that moment. Luckily the girls were easily distracted that day. At least I thought they were. The brunette twin just put away her questions for another time.
As we drove home, she explained that she knew the elf didn't really go back to the North Pole to report to Santa. She told me that she wouldn't tell the blond twin since her Sissy really enjoyed searching for the elf every day.
Now that she knows, the brunette twin is relentlessly focused on the elf. Every day she bounces down the stairs to ensure that the elf moved during the night. Whenever the elf forgets to find a new location, she is happy to remind me. She likes to tease me about the elf's location. She loves being in on the secret.
The other day she was just harassing me about the elf when I turned around and said, "You know, you could move the elf." She smiled and reminded me, "You know that's not true Mom. If a kid touches the elf, he loses his magic. Didn't you read the book?" Then she laughed and walked away.
She's in on the secret, but she's not going to be responsible for the elf. She's happy to leave that to me so she can remind me when I don't do my job. She has the best of both worlds as she keeps the secret for a few more days.
