Also, when *I* was a kid, adults still had enough authority that it was plenty just to say SANTA was watching. When we were sleeping. When we were awake. For GODS SAKE WHEN WE WERE BAD!!!
We didn’t require physical 'proof’. My kids kids will probably have 'Fly on a Wall’. Who reports back to the elf on a shelf who reports back to Santa.
Wait. I think it’s already happened. There he is! A fly! On the wall!
I better not dance naked in the kitchen anymore.
