Love in "Brothers" is measured in comings and goings. The speaker's feelings rise and fall with the rhythm of a brother's visits: excitement when he arrives, tears when he leaves, and a smile that changes the whole mood. The poem never says why he comes and goes. But the phrase "for one or two weekends" suggests the two don't share a home, and that seeing each other is something to look forward to. That is an inference from the text, and it fits the poem's emotional pattern well. Its central idea is that love for a sibling is made of mixed feelings, and that the mixture is a sign of how much he matters. Brothers, the speaker says, "make me, / smile, / cry and, / laugh."
The poem is built on repetition. "Every time you come," "Every time you leave," "And every time you smile" form a chain, each link adding a new feeling. The final line, "I love my brother / every time he laughs," returns to the same phrase and closes the circle. The repetition has the feel of habit, as if these moments happen again and again, and each time they are felt as new. There is also a small step upward from the "smile" of the opening to the "laugh" of the ending, so the poem finishes on a louder kind of happiness than it began with.
There is no rhyme and no regular metre. The lines are short, often only three or four words, and read like speech broken into breaths. The lack of punctuation in "I love my brother, / I really do / he always makes me smile" makes the sentence tumble forward without stopping, the way someone speaks when the feeling is arriving faster than the grammar. The insistence of "I really do" sounds like a person who wants to be believed. The speaker doesn't dress the feeling up. The plainness is a choice that suits the subject, because affection between brothers is often shown in small, ordinary ways rather than in grand declarations.
The most striking image is the rainbow. "Every time you smile, / it's like a rainbow, / even though, / there might be no rain." Normally a rainbow needs rain, so the line plays with expectation. One reading is that the brother's smile brings brightness where nothing needed clearing away, joy without any sadness before it. Another connects it to the tears in the lines just above: tears are a kind of rain, and the smile arrives like the colour that follows. Either way, the odd comma after "even though" makes the reader pause, as though the speaker is stopping to think about what has just been said. That small hesitation is one of the most thoughtful moments in the poem.
The pronouns also move. The opening lines speak directly to the brother ("you come," "you leave"), as if he were in the room. Midway, the speaker turns to someone else, perhaps the reader, and talks about "my brother" and "he." Then the title's plural, "Brothers," widens the lens, and the speaker generalises from one person to a whole relationship. The shift from "you" to "he" can feel like a slight distancing, and it matches the theme of absence. When he is not there, he can only be spoken about.
That absence is handled gently. "Even when he doesn't come, / for one or two weekends. / I love him all the same." The numbers "one or two" are small and concrete, the language of someone counting the days. The speaker admits the disappointment of a missed visit and then sets it aside. This creates a mild tension with the final line, where love is tied to "every time he laughs." The love is constant ("all the same"), yet it seems to be renewed in each happy moment. Both can be true, and the poem lets them sit side by side.
What makes "Brothers" worth reading is its honesty. It does not try to be clever or grand. It catches a feeling most people recognise, the way one person's arrival and departure can set the emotional weather of a week. The rainbow with no rain is the poem's one flash of invention, and it is a good one, because it says in a single image that this brother's smile is a gift and not a reward for getting through something hard.
