The speaker is sitting in a café and quietly watching two strangers at the next table. Nothing dramatic happens at first. A woman has been crying, a man eats a muffin, and the speaker notes small details: her fluttering hand, the stain on her blouse, the empty paper bag, the yellow cup. The man seems oddly calm, even careless, wiping his hands on his thighs while she is clearly upset.
The flat, reportlike lines make the scene feel observed rather than explained. We never learn what the couple's trouble is, and the speaker doesn't guess. That restraint makes the ending land harder. When the man finally opens his mouth to speak, the woman cuts him off with "No. Never. No." The speaker admits to overhearing, as the title hints, and seems caught between embarrassment and fascination. The mood is tense and uncomfortable, a private pain suddenly exposed in a public place, and we are left to imagine what he was about to ask.
