why? because they are smarter than your kids? because i am honest with them? Christmas doesn't stop, just the false idol of the fat home invader.
I'm calling bull shite on you having kids, because if you did, you'd know that elementary aged school kids spend a LOT of time in the world of make believe, and aren't making the logical extrapolations that you are guessing they are.
Also, you are a douche, so hopefully you never plan to have any either.
To the OP, that was a dick move by the dad, assuming that they were both on board with the Santa/Easter bunny thing before they split up. But there are always two sides to a story, especially a Facebook one.
