How does the description of the setting in the opening paragraph reflect the drama in the End of Something?

The narrator's description of how a thriving enterprise, a lumber mill, closed abruptly when the timber was depleted, prefigures how Marjorie and Nick's relationship will abruptly end.
In the first paragraph, Horton's Bay is recalled as a hive of activity; "no one who lived in it was out of sound of the big saws in the mill." The mill dominated the landscape and the lives of people in Horton's Bay. Then, with little warning and even less fanfare, it ceased operations and its remnants were loaded on a schooner that sailed away. At the end of Nick and Marjorie's relationship, Marjorie takes the boat and departs in a manner that is not dissimilar to the way the narrator describes the shutdown of the mill. Both "ends" are described unemotionally; the drama in both cases is muted. Nick tells Marjorie that their relationship isn't fun anymore, and it ends without argument.
