Ok, so let's lighten up a bit.
Write five short, one sentence summaries of a story involving trouble and/or betrayal. Just something quick and dirty. Boy meets girl, she leaves him for a better offer. Woman gets left at bus station by her lover. Bank manager discovers the vault empty and his car gone.
Time to write a noir poem. Expand your sentence into a narrative, with seedy metaphors, slang-ridden similes and cheap thrills. Imagine yourself in a cheap B-Movie extravaganza, living your life on the edge. Roll out comparisons of a dame to... just about anything your mind can imagine. Think seedy and cynical.
