Final answer:
Cloudy days bring a change in weather and mood as described in various passages, with gray skies and rain that can occur while one is indoors, as inferred from wet streets after a movie.
Step-by-step explanation:
From the various passages described, we can infer that a cloudy day in different settings brings with it not only a change in the weather but also a shift in ambience and mood. Descriptions such as a 'gray and overcast' sky, the 'rain pounding the pavement,' and the setting sun obscured by a 'purple cloud-bank' evoke the tangible presence of cloudiness impacting the environment. In particular, the excerpt mentioning an inference about stepping outside after a movie to find the streets wet suggests that it likely rained while the individual was inside. This ties into the idea that cloudy weather often precedes precipitation, affecting not just the physical world, but also the emotional landscape of the characters or individuals who inhabit it.
