I have fallen into a parallel universe where instead of me trying to convince DS that Santa is real, he is trying to convince me.
It's a little surreal.
We have always told DS (now 6 yrs) that Santa is a traditional story and not real. We do the whole stocking thing when we have Christmas in Ireland (mostly because my DM loves doing it) but not on alternate Christmasses when we go to DH's family in Malaysia.
Christmas 2008 was in Ireland and we took DS to see a really great Santa (tbh I was nearly convinced he was the real thing). Since then DS slightly narrows his eyes at me when I refer to Santa being a story. This year I am having the full evangelical experience as he is coming home from school with "proof" of Santa's existence. Apparently Santa has all the parents' phone numbers and will phone them to check whther the DC have been naughty, and when I get the call I will have to believe.
