Most definitions try to sound neutral. "What This Is" starts like one and soon stops pretending. Its first sentence, "It is the deliberate / act of folding / oneself," describes love as shrinking: a person making herself smaller and flatter so she can slip into "the cracks of his heart." The central idea comes in the last three lines. People are "not glue," and they "will not fix / what is already broken." Most of the poem shows why anyone would need to be told this.
The structure is a chain of definitions, each starting with "It is." The first two are built around the word "act": the "deliberate / act of folding" and the "holy / act of praying." The repetition makes devotion sound like a ritual, something performed on purpose. The word "deliberate" matters here. The speaker does not describe someone swept away. She describes someone making a choice, which gives the poem its sting. The third "It is" drops "act" and names a plain feeling, "hoping he will keep you," and then comes the flattest line in the poem: "and it is dangerous." There is no image to soften it. After so much figurative language, the bluntness lands like a door closing.
The images are physical and slightly violent. To "press the creases" is to make a fold permanent, so the self is treated like paper or cloth that will keep the shape it is forced into. Her creases meet his cracks, and the hard *cr* sounds link the two kinds of damage. She injures herself to fit into his injury. The religious vocabulary ("holy," "praying") turns his heart into a shrine and her into a petitioner. Her prayer is also strangely passive: "if you stay long enough." She hopes to be loved by lasting, not by being asked to stay. The poem tells us nothing about what he does. We see him only through his heart, his flesh and the pronoun "he," so the attention stays on her.
The phrase "the flesh will hold you / together" shifts the metaphor in a revealing way. Cracks suggest something hard, like china or plaster, but flesh is soft and living. Judging by the wording, the speaker hopes his brokenness will behave like a wound that closes around her, so that his body will stitch her into one piece. The line break leaves "together" alone at the end of its sentence, a small irony, since the word for wholeness is the one left isolated.
The pronouns move in a similar way. The poem begins with the impersonal "oneself," slides into "you," and then arrives at "Darling." That word is tender, but it also turns description into advice. The voice could belong to someone speaking to a younger self, or to a friend, and the poem does not say which. Either way, the register changes from definition to warning, and the speaker sounds as if she has learned this the hard way. The final metaphor, glue, comes from outside the earlier imagery of folds and cracks, yet it explains them. Glue is what the folded person was trying to be for him, and what she hoped he would be for her. The break after "are" gives "not glue" its own line, and "already" in the last line places the brokenness before the relationship began.
The form supports this. The poem is free verse, with no rhyme and no regular beat, and its short lines break where the sentences lean forward. "Oneself," with its comma, sits alone on its line like something folded small. Soft sounds run through the first half, as in "folding," "fit" and "flesh." Breathy *h* sounds gather around "heart," "holy," "hold," "hoping" and "he," so the poem seems to sigh as it prays.
What makes the poem worth studying is how much it does in so little space. It challenges the familiar idea that the right person will complete you, and it does so without mocking the speaker. "Holy" treats her devotion with respect, and "Darling" speaks to her gently. Her mistake is shown as an understandable hope that goes wrong. The poem ends on a line short enough to remember, and it works because its imagery has already shown, fold by fold, what the line means.
