Or is it the last shadows of summer? No doubt we'll get more sunny days but the sun is losing its heat as it moves steadily south and even the shadows are not as crisp, deep and intense as they were during the heatwave, and that summer heatwave seems like a lifetime ago.
Never mind, the mornings are drawing in rapidly and the clocks have gone back one hour, the evening dog walking times will have to be revised so that they go out a little earlier until finally on a dull day it's dark at four o'clock in the afternoon.
Although I love those long summer evenings there is something about the atmosphere of the darker evenings, well after all it is fire-lighting time and woodburner has been cleaned up, serviced and is tested and ready to go.
There's always a bright side after all.
