Something just occured to me. The Ex hasn't said "Bah Humbug" to me at all this year.

Whenever I've put on my Santa hat to go out, he could be depended on to say "Bah Humbug." I'd just say "mmmhmmm" and go on with my day.

This year he's gotten all the presents, and has assured Older Boy that he'll find a way for Santa (!) to make his way into the house. Later on I'm taking a tree to set up while they're asleep.

Has anyone 'round you had a Grinch transplant, 'cause this is weirding me out a little.
