The mention of geese heard overhead reminds me that I was doing my Christmas shopping in Lancaster in the late afternoon of the 22nd (I think, it's all a blur now) of December. There was fog and suddenly heard the sound of geese flying over above the noise of the crowds and cars.
It was an almost magical experience to contrast the commercial christmas scene presented to the eyes with the hidden natural world that was above the fog. It brought you back to reality with a bump.
