Four lines are all Harbor needs to stage a small, unsettling act of intimacy. A speaker sits close enough to another person to take inventory of their scars, and by the end promises to add one of their own. The poem never says who "you" is, but the closeness of the gesture suggests someone the speaker knows well. What gives the poem its tension is that the speaker's attention is tender and threatening at once.
It begins gently. "I count your scars" is short and plain, with no adjectives and no explanation. Counting is what we do with things we value or fear to lose, and it implies patience. The second line gives the scars a meaning: they are "the ones you've got to mark your strength." The phrasing is slightly off-balance, and it can be read two ways. Scars are what the other person has, and they are also what the person has *got to* show, like proof they were made to collect. Either way, the speaker does not treat the wounds as shameful. They are evidence of survival. The speaker is, at least for a moment, an admirer.
Then comes the word that changes the mood: "Lazily." Nothing else in the poem is so casual, and it sits oddly beside what follows. Drawing "an 'X' over your heart" is a small, offhand movement, as if the speaker were doodling on skin. But an X is one of the most loaded marks there is. It can mean *here is the treasure*, it can mean *crossed out*, and it can be the sign for a kiss at the end of a letter. Placed over a heart, it also looks like the crosshairs of a target. The poem does not choose between these meanings, and the lazy tone makes them harder to separate. The speaker may be tender, careless, or cruel, and the offhand manner makes it hard to tell which. Quotation marks around the "X" add to the effect, since they make it feel like a symbol the speaker is deliberately handing us.
The last line is the poem's turning point: "Here, right here is where I'll leave mine." The repetition of "here" works like a pointing finger, and we can almost feel the fingertip pressing on the spot. The word "mine" is ambiguous. The most natural reading is "mine" as *my scar*, which means the speaker is announcing that they will be the next wound. A gentler reading is that the speaker will leave their own mark, or even their own heart, in that place. The poem's grammar supports both. It moves from "I" and "your" in the first lines to "I'll" and "mine" at the end, so the pronouns shift from observing someone else to claiming a place in their history.
The form is spare. There is no rhyme at the ends of lines: "scars," "strength," "heart" and "mine" do not match. But "scars" and "heart" share an open, ringing vowel, so the first and third lines are quietly linked, and the wound and the place it will land are tied together by sound. The line lengths swell and then shrink. The second line has a steady, almost iambic pull ("The ones you've got to mark your strength"). The third stretches out, as lazy as its adverb. The final line slows into three heavy beats on "Here, right here." The semicolon after "heart" holds the sentence open for a moment before the speaker commits to a promise that might be a comfort or a warning.
The poem is significant because it complicates a common idea. We often say that scars show strength, and the second line does too. But the poem asks what it means to be close to someone who has been hurt before, and it admits that closeness has its own risk. The speaker honors the other person's past while quietly planning to become part of it. The poem is honest enough not to say whether that is love or damage, and the reader is left to decide what the X really means.
