I've been thinking about this for the longest time, and I think the only answer I can give is that I love Christmass because it is an expression of love in its purest form. It may be expressed through shopping or cooking or a million other things, but to me it boils down to love. To borrow an overused phrase, it's something the world needs more of. There's a magic to it, for me, which transcends anything material. I'm not sure all this makes any sense, but it's the closest I can come to expressing it.
Is it all real? Ah, Virginia, in all this world there is nothing else real and abiding.
