In this poem, warmth behaves less like a feeling and more like a lodger with unreliable habits. The word never appears in the body of the text. We only get "It," and the title, «Warmth», works like the answer to a riddle. That small trick matters, because the poem then complicates the answer. "It leaves me in the morning and returns at night" reverses what we expect, since warmth should arrive with daylight. Judging by this imagery, the poem is probably not about temperature alone. It seems closer to an inner comfort, a sense of being held by the world. Its central idea is that losing such a thing rarely happens in one dramatic moment. A daily rhythm slowly loosens until it stops.
The personification is full of mixed feelings. Warmth "loves the sun but resents how bright," so it is drawn to light and bothered by it at once. It is "sometimes pleasant, other times unwelcome," which means the speaker doesn't simply long for it either. This is a believable, awkward relationship rather than a sentimental one. Then the verbs get heavier. Warmth "takes away my soul, when darkness beckons." "Beckons" is a soft, almost polite word for something dangerous, as if darkness were a person at a door. The pronoun also slides here. In "Sometimes returning it as I wake," the "it" is the soul, yet it sits in the same grammar as warmth. The poem quietly lets the two merge, so that losing warmth and losing the self become hard to tell apart.
The form supports this. There is no regular rhythm or rhyme scheme, though "night" and "bright" in the first and third lines flirt with a pattern that the rest of the poem never completes. Nothing else answers them, and the missing echo feels like a promise left unkept. The opening lines are long and steady, with the first stretching to about twelve syllables, and they have the flat calm of someone describing a routine. The repeated "Sometimes" (pleasant, returning, keeping) rocks back and forth like a seesaw. Predictability, even bad predictability, is a kind of comfort, and the poem lets us settle into it.
Then the structure breaks. "Sometimes keeping it until the next day" leads into three fragments, each on its own line: "The next week. / The next year." The repeated "The next" works as a countdown, and the stretches of time grow from a day to a week to a year. The short lines and the white space after them do the work of the passing time. Nothing is described, only counted, and the counting is more chilling than any description of sadness would be.
The final line, "It wasn't coming back," lands because of a change in tense. Until now the poem has been in the present habitual, with warmth leaving and returning as if it always would. Here the speaker turns to the past. "Wasn't" suggests someone looking back from the far side of the loss, who can now see that the earlier "sometimes" was a false comfort. The line is also ambiguous. It could refer to warmth, to the soul, or to both, and the poem doesn't choose. There is no exclamation and no explanation, just a flat statement.
The name printed above the poem is a farewell phrase, an echo of the Spanish "hasta la vista," which means roughly "until we see each other again." I wouldn't guess at the story behind the name, but the echo is hard to ignore. The poem is a goodbye that removes the "until."
What makes the poem worth reading is its restraint. It never says what has been lost or why, so readers can bring their own loss to it, whether a mood, a person, or a time of life. It manages this in nine short lines, by turning a pronoun into a presence and letting the line breaks do the mourning.
