Praise poems usually pile up compliments. "Smile." does the opposite: it starts by taking one away. The speaker says he was in awe of the woman's smile, "Not because of how chalk-white / her nice teeth were." Having mentioned her teeth, he pushes them aside and moves on to something he finds harder to measure. Her smile, he says, was "an accurate representation of perfection and innocence." The poem is about how a small, wordless gesture can change the weight of a bad day, and its central idea is that real beauty lies in what a smile does, not in how it looks.
The word choices are worth slowing down for. "Nice teeth" is a plain, almost shrugging phrase, and it works because it is so ordinary. The speaker isn't trying to dazzle us with the surface of things. "Chalk-white" is more interesting than a stock comparison like "pearly". Chalk is matte and dusty, and it is what we use to make marks on a dark board. That picture quietly anticipates the poem's contrast of light against dark. Then comes the oddly formal "accurate representation." It sounds like a word from a laboratory or a courtroom, and it suggests a speaker who wants to get this exactly right, as if exaggeration would insult her. Set beside "perfection and innocence," the cool phrasing makes the praise feel carefully considered rather than gushing.
The poem is written in free verse. There is no rhyme and no regular metre, and it reads like speech. The ellipsis in "I mean...no matter how dark it was in my life" is the clearest sign. It sounds like someone pausing, half-embarrassed, before saying the true thing. The line lengths do the rest of the work. The third and fourth lines sprawl, with the speaker explaining and qualifying as he goes. Then the poem drops to "She would simply smile," a short, calm line that copies the effortlessness it describes. The word "simply" matters here: she doesn't have to try, and the poem barely does either. The last line is the longest, and it spills across the page the way the light it describes spills into a room.
That final image carries the poem's most striking choice of verb. Darkness is "devoured," which is a violent, hungry word, and it is the light that does the devouring. You might expect a gentle smile to chase shadows away politely. Here, darkness is eaten. That tells us how heavy the speaker's dark times must have felt, since only something with real force could consume them. The poem never says what the darkness was, and that vagueness is a strength. "No matter how dark it was in my life" can hold grief, loneliness, fear or plain exhaustion, so any reader can slot their own troubles into the gap.
The tenses also change quietly. The poem opens with a single moment ("I was in awe") but moves into the habitual "would simply smile." This is something that happened again and again, and the repetition suggests reliability. The speaker isn't describing one lucky moment; he is describing someone he could count on. Even the capital "She" in the middle of a sentence gives her a small extra emphasis, though that may be a quirk of punctuation rather than a deliberate gesture.
The title adds one more layer. "Smile." with its full stop could be a noun naming the subject, or it could be a gentle command. Read as an order, it asks the person, or the reader, to pass the gift on.
What makes the poem significant is its refusal to complicate things. It tells us nothing about who she is, what she looks like beyond the teeth, or what the speaker's troubles were. It keeps only the exchange: darkness in, light out. In that restraint it makes a modest but believable claim, that kindness doesn't need to be grand to be life-changing. For a student reader, the poem is a good model of how plain words, a few well-placed images and one strong verb can say something sincere without sounding sentimental.
