Every line of "Understand Behavior" makes a boast and then takes most of it back. The speaker lists seven virtues (purity, action, loyalty, honesty, laughter, kindness, thoughts), and each time the last word or two, cut off by a comma, quietly shrinks the claim. The result is a self-portrait by someone who cannot help admitting that the portrait is flattering. The title works as an instruction to the reader. To understand this person's behavior, you have to read the gap between what they declare and what they confess.
The construction is almost mechanical. Each line has three parts: an abstract label ("Loyalty"), a claim ("I'd Never runaway from those I whole dear"), and a hedge ("Most days"). The pattern is so regular that the hedges become the real subject. "Almost innocent" sounds like a small modesty, but it concedes that the "pure" intentions are not quite pure. "Sometimes" is a more damaging qualifier for noble actions, because nobility that comes and goes is hardly nobility. "Most days" turns loyalty into a timetable, as if devotion had days off.
The sharpest moments come when the claim and the hedge flatly contradict each other. "I'd never make you doubt or worry" is followed by "Few times", so the speaker promises never and then admits to a few. "Laughter, I'd Never make you cry, Intentionally" is cleverer still. The final word rules out cruelty, but it leaves open the possibility of hurting someone by accident, or carelessly, and it hints that this has happened. Then "My Thoughts and feelings are always genuine, Maybe" sets "always" beside "Maybe", the two least compatible words in the poem. Notice too that "genuine" is not the same as "kind". The label promises kindness, but the line only vouches for sincerity.
There is no rhyme and no steady meter, and the rhythm comes from repetition. "My", "I'd Never" and "always" return like a refrain of absolutes, and each is answered by a short, deflating tag. A long confident clause followed by a thud gives the poem a stumbling, comic-sad pulse, like someone who starts a speech boldly and loses their nerve at the end of every sentence. The language also has a rough, unpolished texture. "Runaway" is written as one word, and "those I whole dear" reads like a slip for "hold dear". Capitals fall in odd places ("Never", "Intentions", "Hallucinations"). Whether deliberate or not, these quirks make the voice sound spoken and unguarded, closer to a confession than a speech.
Imagery is sparse until the final line, which is where the poem turns. "Thoughts, My Hallucinations are always pleasing, To sinners." The label promises thoughts, but the line delivers hallucinations, so the speaker's own mind has slipped from reason into vision. The last hedge also differs in kind from the others. "Sometimes" and "Few times" lower the frequency of a virtue, but "To sinners" changes the audience. The speaker's inner world is pleasing only to a certain sort of person, and this accuses the reader as much as the speaker. Anyone who enjoys these hallucinations must be a sinner, and the poem ends by turning its judgment outward. It is also the only line to bring in explicitly moral, religious vocabulary, which makes that final word land hard.
Nothing is supplied here about when or why the poem was written, so the text has to speak for itself. The byline, with its "Dr." and its wintry "FrostBite", reads like a persona, and the title sounds like a clinical instruction. Judging by these, the poem plays at diagnosis, with the speaker acting as both doctor and patient, charting their own symptoms and softening each one as they write it down.
That is what makes the poem worth reading. It shows in seven short lines how a single word can reverse a sentence, and how self-flattery and honesty can sit in the same breath. Most of us could write the first half of each line, "my intentions are pure" and "I'd never make you cry". The poem's insight is that the real character shows in the small word we add afterward.
