Fredhatt's poem sorts everything we meet into three groups: things we want, things we avoid, and things that simply don't matter. The tone is almost like a lab report at first. The speaker lays out the categories with labels, A, B and C, as if describing a simple machine. Our minds, the poem says, chase the first group, fight or run from the second, and barely register the third, which fades into "the walls of our Maze."
That image is the heart of it. Because we're so busy hunting and dodging, most of the world becomes mere background, something we pass through without noticing. The final stanza shifts the mood sharply. When we actually look at those ignored C things, the world turns into "a river of wonder." The speaker seems quietly convinced that attention is the way out of the maze. The poem starts cool and analytical, then ends in a gentle, open-hearted sense of amazement.
