Six short lines are enough for Dave Bonta to hold a whole way of life: the poor student, rich in reading, shuffling around in a gown while the weather waits outside. The poem looks back on those days with amused affection, and its central idea is a gentle paradox. Having almost nothing can feel like having plenty, as long as the mind is fed, yet the body still has to step out and pay for that richness in the cold.
Everything hangs on the opening metaphor. "books were my oysters" echoes the familiar saying that the world is your oyster, but it shrinks the world to something private and edible. Oysters are a luxury food, the kind you buy when money is no object, and this speaker has "little money." Books become the feast he can't otherwise afford. The image carries more than that, too. An oyster is a closed shell that has to be pried open, with a soft interior and the chance of a pearl. Judging by the imagery, reading is being pictured as patient prying, and the student as a creature at home inside his own shell.
The syntax supports this feeling of enclosure. The poem is one unpunctuated sentence spread over three couplets, with no capital letters except the pronoun "I" and no full stop at the end. The line break after "money" lets the poverty stand alone for a beat before "I was content" answers it. Contentment is the only emotion the poem names, and it is stated flatly, without exclamation. The past tense ("were," "was") suggests an older speaker looking back, so a reader may wonder how far to trust that contentment. Is it the memory of real happiness, or a kind and slightly self-mocking editing of the past?
The second couplet gives the poem its comic picture. A "gown" could be a dressing gown, which suggests comfort and idleness, or an academic gown, the costume of scholarship worn absurdly as everyday dress. The poem doesn't choose, and the ambiguity helps. Either way, this is someone dressed for the life of the mind. "indoors all day" is made almost entirely of heavy, equal beats, so the line itself seems to sit still.
Then comes the strangest phrase in the poem: "go out with my legs / into the cold." A gown covers the body but leaves the legs exposed, so the detail is physically funny and a little shivery. "Go out with" is also what people say about dating, and here the speaker's only companions are his own legs. The phrase also splits the person in two. The legs go out into the world while the real self stays behind with the books, as if the body were merely transport for the head. The joke has a truth in it, because a studious life can treat the body as an afterthought.
The sound and shape of the poem are quietly effective. There is no rhyme and no regular metre. The lines run from four to eight syllables, and the longest, "I was content to wear a gown," is the one that describes comfort. After it the lines shrink to "indoors all day" and "into the cold," as though the poem were contracting under the chill. The rounded vowels in "content," "gown," "indoors," "go" and "cold" give the poem a low murmur that makes the last word land like a door swinging open. Because there is no full stop, the cold is never resolved. We leave the speaker out in it.
What makes the poem worth reading is how little it asks for sympathy. It could have complained about poverty or gushed about the love of learning. Instead it keeps both feelings in view and trusts a few concrete details, the oysters, the gown and the bare legs, to do the work. Its economy also mirrors its subject, since a poem about living on little is itself built from very little. Anyone who has ever chosen an absorbing passion over comfort will recognise the bargain it describes, and may smile at how cold the walk always was.
