My text from the Advent windows entry on the face book page:
Winter Solstice brings the shortest day, and today's photograph, although not quite the shortest day (it was taken yesterday), illustrates the delights of a mid-afternoon sunset along the Embankment. From here-on-in, each day will have more light but the increments are tiny to start with. Tomorrow will be just a few seconds longer than today and we will be unaware of the difference.
Sometimes, we are impatient for big changes to happen once we have turned a corner, but although the path may be certain, the progress can take time to decipher. If you identify with this - hang on in there - the important thing is that the corner has been turned, the right decision made, the wheels set in motion.
@flowerfairyann Ann thank you for your comment. Yes this is a bridge - I have featured it a few times in my photographs. Just a short walk along the river from yesterday's bridge.
Very nice Advent window!
