My son was standing in the kitchen the other day sticking his tongue out and making horrible faces. I asked him what he was doing. He said, "The elf can't see me in here."
We have an "Elf on the Shelf" who was hanging out in the dining room that day. My son had been making faces at his sister who informed him the elf was watching. He sought refuge in the kitchen where he could express himself without risk of being reported to Santa.
The kitchen really is the soul of the house!
