You'd better watch out!

On Christmas Eve last year, Elder Son said to me, “My friend has a way to find out if a Santa is a fake Santa. First, if his beard is fake. Second, if he asks what your name is.”

I nodded. “Well, you know those pictures of me with Santa at the tree farm? I was working a remote broadcast for the radio station, and he came looking for me.”
I continued with a voice touched with awe. “He had a real beard, and he knew my name… even though I’d never met him before.”

The Elder Son leveled a look at me. “Could it be he knew your name… because you’re on the radio?”

(Dang, he’s sharp!)
