My secrets are metaphors. The words are artfully arranged in alliteration Or cautiously halted in Enjambment so that they don't reveal themselves.
My secrets are anaphoric. They are metonymic, swearing secrecy to the pen. Sometimes they are synecdoches, Begging, afraid, in rhyme for your attention again.
My secrets are anecdotes. They write about themselves through personification. This poem juxtaposes itself; I've told you all of my secrets of secrecy-how ironic.
