"And covered up our names...."
See in text (Text of the Poem)
The speaker suggests that death has covered up their names and that their voices have been lost. However, what is ironic is that the poem is being read and their voices have already been preserved in writing. The speaker tells us from the beginning of the poem that they are dead, so they have been speaking from beyond the grave for the entirety of the poem. This further cements the poem’s theme that death need not be scary or sad. It is merely a fact of life, and our ideas may persist after our bodies die.
