The advice at the centre of "Pretty Nails" sounds almost kind. A child confesses to a habit, and her grandmother offers a fix: paint them, because "Pretty girls don't have ugly nails." Wynne DM builds the whole poem on what that fix leaves out. Nobody asks why the speaker bites. She has already told us, in the single-word lines that open the poem: "Nervous / Angry / Scared." Her grandmother treats the symptom as a flaw in appearance and never touches the feelings behind it.
The poem's key word is "pretty," and its meaning darkens each time it returns. It begins as a compliment, then becomes a rule. After that it turns into a costume: "Pretty in my final gown." By the end it is a container, "a pretty coffin in the dirt." The word appears in the title, in the grandmother's sentence, in the parents' "pretty words" at the imagined funeral, and in the "pretty girl's smile." The repetition shows how one idea can spread through a whole life, from nails to smile to sense of self. Even the eulogies are trapped in it. They would praise "the pretty girl / With the ugly nails," so even in death the praise and the pain sit side by side and never meet.
The imagery pivots on one colour. The polish is "red like my bleeding nail beds," so the cover-up and the wound are almost the same shade. The polish does not truly hide anything, because it looks like the damage it covers. The red then turns into the poem's most unsettling image: the speaker "scratching on a coffin / Desperate to escape the suffocation / Of being six feet under." Nail-biting becomes the frantic clawing of someone buried alive. The funeral fantasy that follows is bleak in a quiet way. She imagines herself "underground for no one to see," which suggests the real fear is being unseen, not simply dying.
The form is free verse with no rhyme, and the plain, speech-like diction suits a voice that begins "See... I have a nail biting problem," as if she were bracing for a reaction. The lines are short and mostly end-stopped, so the poem moves in small, hesitant steps. The ellipses in the opening ("See...", "when I was...") come back at the close, now as "scratch... scratch... scratch...", where the trailing dots make the action seem endless. Earlier, the full stops in "Scratching. Scratching. Scratching." make the word land like a repeated blow. The sound of the line is the compulsion itself.
The most carefully shaped passage is the triple structure near the end: "My bleeding, bitten nails... My bleeding, bruised heart... My bleeding, broken self esteem." The repeated "My bleeding" and the b-sounds (bitten, bruised, broken) carry the reader from the visible body to the hidden self. The verbs around these lines stay flat and cold: the polish "disguised" the damage, the smile "hid" the heart, and the self-esteem was "encased." That last word sits at the end of its line, and the enjambment, with "In a pretty coffin" falling to the next line, makes the reader feel the enclosure. Tense matters too. The childhood story is told in the past, but "I imagine" and "All I can do now" bring it into the present, which suggests the lesson has outlived the grandmother's moment. The final line, as printed, reads "Until my nails or polished red again." The "or" is presumably meant to be "are." Either way, it closes the cycle: bitten, painted, bitten, painted.
What gives the poem its force is its restraint toward the grandmother. She is not painted as cruel, and her words are simply reported. The harm comes from how ordinary and well-meant the advice sounds. Many readers will recognise the message that looking fine counts for more than being fine, and the poem shows what that message can cost: a self that learns to hide and starts to feel buried. It is a small domestic scene that grows into a metaphor about living behind a surface. Its slightly rough, unpolished edges feel fitting for a poem that argues against polish.
