Let the children have their night of fun and laughter. Let the gifts of Father Christmas delight their play. Let the grownups share in full their unstinted pleasure before we turn again to the stern task and formidable years that lie before us.
Christmas is taken very seriously in this household. I believe in Father Christmas, and there's no way I'd do anything to undermine that belief.
We used to indulge hopelessly as a family at Christmas. When the children were little, I dressed up as Father Christmas. They knew it was a gag, but they loved it. I remember stealing into their bedrooms at 1 A.M. and filling the stockings up at the end of the bed.
So it is best to keep an open mind and be agnostic. At first sight that seems an unassailable position, at least in the weak sense of Pascal's wager. But on second thoughts it seems a cop-out, because the same could be said of Father Christmas and tooth fairies. There may be fairies at the bottom of the garden. There is no evidence for it, but you can't prove that there aren't any, so shouldn't we be agnostic with respect to fairies?
There I am, watching Philip Seymour Hoffman, one of my favourite actors in the world, walk into the room dressed up as Father Christmas, being hilarious, and I'm suddenly thinking, 'Where am I?'
I think Father Christmas is real because the belief is real. The belief becomes the reality.
I want to go to Lapland and see Father Christmas, and now I've got a child, so I've got an excuse. Also, I'd like to go to South America especially as I'm now living in that part of the world, in L.A. now. And I must get down to Mexico.
What I'm not saying is that all government spending is bad. It's not - far, far from it, but there is no free lunch, as a former colleague of mine used to say. There is no public tooth fairy. Father Christmas does not work on the Treasury staff this year. You can never bail someone out of trouble without putting someone else into trouble.
I suppose if you look back to your early childhood you accept everything people tell you, and that includes a heavy dose of irrationality - you're told about tooth fairies and Father Christmas and things.
We don't consider the Wizard of Oz or Father Christmas to be too old. They're still magical characters, and the fact they've been around the block only adds to their magic.
