Dave Bonta's short poem treats a pile of papers as something oddly comforting and oddly ominous at once. The speaker calls it a "nest," a word that suggests warmth and shelter, something built up around you over time. But the second image is darker: the papers are "convenient as one's own pale horse." The pale horse is the rider of death from the Book of Revelation, so the speaker is joking, a little grimly, that death has a handy ride waiting nearby.
The middle lines hold the poem's tension. The papers are "not yet dead / but open to it," which could describe the writing itself, still unfinished and vulnerable, or the speaker, who feels close to the edge. The last image turns the pages into "an ink body" that will carry the speaker off at night. The mood is quiet, dry and a little eerie. The speaker seems calm about it, even gently amused, as if writing is both a refuge and a way of imagining one's own passing.
