Dave Bonta's four lines take the grand idea of a creation story and shrink it down to something oddly familiar: the office. Instead of a divine spark or a bang, the universe's beginning is a workplace arriving. The sun, "a great dirty star," pushes into a night that the poem pictures as a coffee-house, a place of dim light, slow talk and rest, belonging to "our mother night."
The joke is gentle but it has an edge. Night feels like home, warm and unhurried, and daylight is an intruder that brings schedules, duty and grime. The word "dirty" suggests the speaker isn't awed by the sun at all, more weary of it. Judging by the tone, there's a dry, wry affection for the dark and a mild grumble about the working day.
The mood is playful and a little melancholy. By calling the sun's arrival the "first office," the poem hints that work is as old as the cosmos, and nearly as hard to escape.
