What is the theme in Portrait of a Couple at Century's End by Sherod Santos?

Empathy is an important theme in the book. In the fifth stanza, in line 24, “Portrait of a Couple at Century's End” changes direction. Lines 1 through 23 focus on one continuous scene: a suburban home with cars going by in the rain and the news on the television while a couple eat their dinner and placidly discuss their day. In line 24, however, the speaker intrudes on the story. “They remind us / of something” draws attention to the fact that the poet is describing a scene and that the reader is observing it. In lines 24 through 32, the poem uses the words “us,” “we've,” “our,” and “ours” to make readers see how the poem is talking not only about the lives of theoretical people but also about readers' lives.
