How My Boy's Mind Works, Vol. 32568:
Picture it. M1 and I are in the van today, getting him a haircut, grocery shopping, and going to the bank, and he suddenly announces out of the blue, "St. Nicholas."
"St. Nicholas?" I query suspiciously.
"Yes. St. Nicholas is Santa Claus, right?"
"Well, St. Nicholas was alive a LONG time ago. He should be dead.
"But if he's Santa Claus, that means he's still alive.
"But if he's still alive, then he can't be a saint."
"Right...," I respond cautiously.
No, really, that was all. He never did press further. But I strongly suspect this is the last year that Santa exists in his world. It's hard to watch him grow, but dang, the logic is amazing.
