Invisibility usually means there is nothing to see. Sam M's "Invisible" argues the opposite: the speaker goes unnoticed because there is so much to see, and so much of it is hidden. "There's always more of you / Than what meets the eyes." The idea is that a person is always larger than the version of them that others notice. The poem then follows what happens when nobody looks past that surface, even someone close.
The structure is simple and relentless. There is no regular rhyme and no steady metre, only short lines in plain speech, as if the poem were being said aloud rather than polished. Repetition does the work that rhyme might otherwise do. The opening line, "You're always invisible," returns almost word for word halfway through, so the poem seems to circle back to the same wound. Between those points comes a run of lines beginning "There's always more": more of you, more emotion, more tears. The word "always" hardens each one into a fact, not a mood. The imagery in this run is of containers. The heart has a limit ("Than your heart can take"), and so do the eyes ("Than your eyes can hold in"). The speaker is a vessel filling past capacity, and all that pressure is invisible from outside.
The second half turns from overflow to injury. "They take a stab at you / Over and over again" plays on an everyday phrase. To "take a stab at" something is to attempt it casually, but here the words also suggest a blade. The people around the speaker may not mean harm, yet the repetition makes the damage cumulative. Then comes the poem's most precise image: "They miss the cracks in your mask." The mask is the self the speaker shows the world, and its cracks are the "quiver in your voice," the small, involuntary signs of pain. The cruelty is that the speaker has partly failed to hide, and even this failure goes unread. Someone can "look you in the eye and miss your pain," so even direct eye contact fails to connect. It is a quiet but painful detail.
The pronouns shift as the poem goes on. Early on, the voice speaks to a general "you," so the poem could describe anyone. Then "the person who knows you best" becomes "they," and finally "He misses who you really are." That last, single "He" is the only point where the poem names a particular figure. Judging by the text, the speaker may have one specific person in mind, though the poem never says who. The shift makes an abstract complaint feel suddenly personal.
The ending is the bleakest part. "When nobody knows / You're nothing" can be read two ways because there is no punctuation. It might mean "When nobody knows, you're nothing," a rule about worth that depends on being known. Or it might mean that nobody knows you're nothing, so the speaker is quietly judging herself or himself. Either way, the sound of "nobody" and "nothing" together shows how fast the logic collapses: unseen becomes unimportant, then worthless. The last line, "A nobody cast aside / For the world to run over," uses a road image. The speaker is no longer a vessel or a masked face but something left on the ground to be flattened. The speaker is also passive here, "cast aside" by someone else, and the poem gives no sign of resistance. Notably, the closing full stop is the only one in the poem. Until then the lines run on unpunctuated, as though the speaker had no chance to pause. The full stop falls where the speaker is finally run over.
The poem is significant because it captures a feeling many readers will recognise without needing any elaborate language. Its power lies in the paradox at its centre, that someone can be overflowing with feeling and still unseen. It also suggests that the real danger of invisibility is not being ignored but coming to believe the ignoring is deserved. The poem does not offer comfort, and that may be why it feels honest. It leaves the reader with a question: how closely do we look at the people who are standing right in front of us?
