Hartley's "Ballad: 'What You Never Knew'" begins with a puzzle: "I've locked myself from the inside out." Normally a lock keeps others out, but "from the inside out" twists the phrase, so that the speaker is both shut in and somehow turned inside out. The next line settles the matter: "Nobody can open the door but me." The speaker is isolated and wounded, yet also in control of the lock. That tension between blame and self-blame runs through the whole poem. The speaker accuses someone, "you," of never seeing them, while admitting to a silence that made seeing almost impossible.
The central idea is the pain of being unknown by the people who should have known you best. The second stanza makes this sharp. "You didn't have the time to understand" and "You didn't have the time to hold my hand" repeat the same opening, so the accusation lands twice, and the second time it moves from knowing to touching. Time becomes the poem's quiet obsession. "You didn't have the time" turns into "By the time you see this," and then into the final "too late." The poem is built around a deadline.
Sight is the other thread. The speaker wants to be seen ("Why is it that you could never see"), then makes themselves "invisible," then accuses the listener of having "turned a blind eye." The question in the first stanza has no question mark, so it trails off rather than demanding an answer. The speaker seems to have given up expecting one. The phrase "painful kiss" is the most ambiguous image. A kiss is normally the clearest sign of closeness, but here it is a gesture that was ignored, or one that hurt in the giving. The poem does not explain it, and the mystery sticks.
The form is more controlled than the emotion. Each of the three stanzas has five lines and rhymes ABAAB: "out / me / about / shout / see," then "understand / best / hand / planned / rest," then "remiss / hate / kiss / this / late." The three A-rhymes in a row make each stanza feel like it is closing in, and the B-rhymes at the start and end of each stanza act like a frame. The last stanza has the most striking sound pattern. "Remiss," "kiss" and "this" chime softly, but the stanza ends on the flat, final rhyme of "hate" and "late." The rhythm is loose and speech-like, with long lines that gallop in threes ("In my silence, I would scream and would shout"). Then, in the last two lines, it shortens to "By the time you see this / It will be too late." The abrupt shortening works like a door shutting.
The title calls the poem a ballad, which is worth noticing. Traditional ballads usually tell a story in short, regular stanzas. This poem tells almost no story. We get no names, events or places, only a voice addressing a "you." It is closer to a personal lyric, and the label may simply point to its song-like rhymes and refrain-like repetitions.
Some lines are blunt or tangled. "Scream and shout" is a familiar phrase, and "You do not know me better than the rest" is hard to untangle. Yet the plainness suits a speaker who has stopped decorating their feelings. "I've never known love, only hate" is an extreme claim, and it reads as the exaggeration of deep hurt rather than a balanced judgment.
The poem's most important move is the way it makes the reader the "you." Lines like "What I've written now has been thought out and planned" and "By the time you see this" suggest a message left behind, perhaps a farewell. That is an inference from the text, since the poem never says so directly. We read it at the moment the speaker imagined, and any lateness is built into the act of reading. That is what gives a modest poem its force. It shows how silence can become a prison, how easily the people nearby can miss it, and how much weight small acts of attention, like having "the time," can carry. If a poem like this reflects something you or someone you know is feeling, talking to a trusted adult is a good next step.
