And seeing that it was a soft October night,
Curled once about the house, and fell asleep.
There is nothing to do on an unimportant autumn evening…
The yellow, cat-like fog curls and falls asleep (i.e., settles) around the house. With intentional dissonance, the image portrays something disgusting (urban pollution) in almost playful, endearing terms.
