A speaker sits across a table from a woman who keeps burning herself with her cigarette. The poem calls it "accidentally," but the word sits alone on its line, and the repeated "again" makes us doubt it. Something is wrong, and the speaker seems to notice.
Then comes the turn: "soon / we'll compare suicide attempts." The speaker doesn't sound shocked. He sounds resigned, even half-expecting it, as if two damaged people are heading toward a grim kind of bonding. The final "ah / romance" is bitterly ironic. Romance is supposed to mean tenderness and sparkle, but here it means shared pain.
The mood is flat, uneasy, and darkly funny. The short, broken lines and the plain coffee-table setting make the dark subject feel casual, which is exactly what unsettles us. The speaker may be using sarcasm to cover discomfort, or even a strange longing for closeness, however twisted.
