In Cummings’ opinion, the ladies do not spend enough time thinking about the things Cummings feels are important, such as “if sometimes in its box of sky lavender and cornerl ess, the moon rattles like a fragment of angry candy.”
The way Cummings describes the moon in this final line is a sharp contrast to the way he describes the Cambridge ladies. He uses an explosion of adjectives to describe the details of the sky and moon; details that this section of society overlooks in favor of meaningless things.
The message Cummings is trying to send with this poem, and with many of his poems, is that details matter.
