The poem is a single sentence distributed across ten lines, and the distribution is the poem’s formal achievement. Each line break adds a beat of delay between the smile’s origin and its destination, so that the reader experiences the instant the title names not as a flash but as a slow-motion event—the way a moment of falling in love feels simultaneously instantaneous and eternal.

The opening—”A beautiful smile / From you”—identifies the cause with radical simplicity: a smile, from you. No context, no setting, no circumstance. The poem strips away everything that isn’t the smile and the person who produced it. “Can make / A home” is the line pair that carries the poem’s entire metaphor: the smile doesn’t visit the heart; it builds a residence there. The verb “make” is active, constructive—this is not a feeling that settles passively but one that builds, furnishes, moves in. A home is permanent infrastructure, not a hotel room.

“In my / Heart” places the home’s location across a line break that isolates “Heart” as both the end of a phrase and the beginning of a new emphasis. The enjambment forces the reader to pause at “In my”—a moment of vulnerability, the speaker opening the door before naming the room.

“and Never / Ever / Leave” is the poem’s emotional payload, delivered in three descending steps that hammer the permanence into place. “Never” is strong; “Ever” reinforces it; “Leave” completes it. The three words function as nails driven into the home the smile has built—each one securing the structure more firmly. The line breaks give each word its own weight, its own breath, its own finality.

“Thank You Valentine!” is the closing and the poem’s only punctuation—an exclamation mark that releases the tension the preceding nine lines accumulated. After the slow-motion descent from smile to heart to permanence, the thank-you arrives as both gratitude and relief: the speaker has received something permanent, and the only adequate response is to name the occasion and say thank you. The exclamation mark is not volume but joy—the sound of a man who has just realized the smile isn’t leaving.

The poem’s relationship to the catalog is one of distillation. Where “I Collapse in a Smile” took thirty lines to trace the Muse’s smile through an entire biography, “In an Instant” reduces the same event to its chemical formula: smile + heart = home. The earlier poem was the feature film; this is the photograph.
