Do you ever sit and just look out your window? What do you see? Where does your mind go? Do you think beyond the street and sidewalk below? Do you consider the multitude of people, beyond your lines of sight? The trees and animals. Nature. Distant land, all different.
Is your window open? Can you hear the city outside? What do you pick out? The sounds of cars, the distinctiveness of buses, diesel engines, a siren? Voices. Are they excited? Maybe a laugh? Can you hear a dog bark from where you sit? Do you listen to the noises coming over the rooftops? How far can you stretch your ears out into that city of sound? At what distance is it just noise? Do you hear that hum?
Do you look up at the sky? What is up there? Clouds? What color are they? Do airplanes fly above your window? Is it night? Is there a moon? Can you see beyond the city glow?
