Today is the shortest day. The sun reaches it's highest elevation at 12:04 before giving up and heading south again (at least that's what it said in yesterday's Times). So from here on in it'll be getting progressively lighter. Yippee. I think that does begin to happen, in quite small ways, quite soon (like, it starts getting lighter again). It'll be noticeable by mid-January.
If I were a pagan I'd be dancing skyclad around an allotment bonfire to celebrate. I can hear the Salvation Army band in the background. Perhaps they know that acts of skycladness are imminent and are here to save me from myself.
But it's too wet for a bonfire and too cold for skyclad. you'll just have to visualise it.
