Throughout the day, I took little breaks to look out the window and watch its gradual retreat.
First the top of the Mendips came into view ...
... then the houses down the hill ...
... and finally the towers of Wells Cathedral on the far side of a distant river of mist.
Then, before we left, it came piling back in again.
And we were rewarded with this.
A reminder, perhaps, that when you can no longer be bothered to go out of your way to find beauty, it might be time to call it a day.
