Dave Bonta's short poem works by quiet suggestion rather than plain statement. It begins with an odd idea: a day set aside "to write backward," so that it turns into "another day." Writing backward could mean literally reversing words, or it could mean looking back, revisiting memory and letting the past reshape the present. Either way, the day doesn't stay the same; the act of writing changes it.
The second stanza shifts to an image of a cake cut into as many pieces as "the moon / in fine frost." That's a strange, lovely comparison. The moon in frost might be pale, glimmering, broken into countless tiny points of light, so the cake seems divided almost endlessly. Paired with the title, "Divide and consider," the poem seems to be about slicing time or experience into small portions so we can look at each one closely.
The mood is calm, playful, and a little mysterious. The speaker seems contemplative and gently curious, treating an ordinary day as something to be sliced, shared, and savored.
