I was 18. It was my last Christmas at home before I moved in with my new husband :-)
What age were you when you got your last stocking / present off Santa?
Did I misunderstand the question? I stopped believing in Santa at age four; I couldn't get to sleep and the words to the song were on my mind: "He SEES you when you're sleeping. He KNOWS when you're awake. He KNOWS if you've been bad or good. So be good for goodness sake." I was afraid my punishment for being awake would be no presents. Then I saw my parents bringing in the gifts.
"Hail him who saves you by his grace,
and crown him Lord of all."
