Nearly every household has a cupboard that nobody opens carelessly, and Maartje Sofie borrows it to describe something much harder to see: what happens to feelings that are never let out. In "cupboards" the speaker says she keeps her emotions "all stuffed away / in my heart," and the poem then asks how long a person can go on doing that. Its answer is that the system works only until someone forgets it is there.
The poem's most important choice is its comparison. The heart is the standard poetic home for feeling, and the poem names it in the first stanza. But the heart is quickly replaced by "Tupperware in a cupboard," which is plain, practical and a little comic. Tupperware is meant for keeping things for later, with lids and neat stacks and leftovers. The word "stuffed" works against that tidiness, though. Nobody stuffs a cupboard carefully. It suggests shoving things in and pushing the door shut, so the speaker's control looks less like calm organisation and more like a quick fix that has become a habit. The homely image also makes the confession feel ordinary. This is not a dramatic outburst but something that could happen in any kitchen, and that is why it lands.
The poem is built from three stanzas of three lines each, in free verse with no end rhyme. The short lines are close to ordinary speech, and the missing rhyme suits a speaker who is not performing. The rhythm changes in the last stanza, though. The first two stanzas pause at the ends of their lines, but the final one runs on: "And it all comes crashing down / with once quick glance / inside." The opening "And" starts the collapse mid-thought, and the line breaks make the reader tumble from line to line. The sounds help too. The hard *c*, *k* and *q* of "crashing" and "quick" echo the "cupboard" of the title and sound a little like things clattering. As printed, "once quick glance" looks like a slip for "one quick glance." Either way, the meaning is the same: the smallest look is enough.
That contrast is the poem's central idea. A glance takes almost no effort, yet it brings everything down. The disaster isn't caused by a great shock or a deliberate decision but by a lapse in attention, the moment "you forget how full it is." The poem also gives the feelings a kind of patience. They are "waiting for the day," as if they know the forgetting will come. Judging by this personification, the speaker does not think her emotions have gone away. They are only stored, and they still take up space.
The second stanza also shifts from "I" to "you," and the poem never says who "you" is. It could be someone else who opens the cupboard and sets off the collapse, or the speaker talking to herself, or a general "you" meaning anyone who lives this way. The poem leaves the question open, and that fits its theme. The speaker is slightly distanced from her own feelings and seems to describe herself from the outside, as though she can state the danger more easily than she can feel it.
The final word, "inside," sits alone on its line and echoes the "in my heart" that closed the first stanza. The poem begins and ends on the idea of an inner space, first filled and then looked into. The title's plural, "cupboards," and its lowercase letters might suggest that the speaker has many such compartments. That is an inference, but it fits the poem's quiet, unshowy tone.
What makes "cupboards" worth reading is how much it does in so few words. It doesn't lecture about suppressed emotion or name any particular feeling. It trusts a small domestic picture to carry the weight, and most readers will have seen that picture before, with the door held shut and the shelf about to give way. By staying that small and plain, the poem makes the reader feel the pressure of keeping everything contained.
