Who thought: 'Hm, why don't we slosh through the snow to the green and thriving orange tree to fill the stockings?' The answer: no one.
Fruit in the winter? Don't get me wrong, I love fruit, but in my mind, winter is not the season I associate with it. On the other hand, I can't see the same joy from receiving a can of oranges in your stocking. It would make me want to call Santa for a refund.
In the end, the tradition wins, but I always wonder what the people who began these things were thinking. Anyway, I wish you all a Merry Christmas and may your stockings be overfilled with Christmas Oranges!
