I often write metaphors on my Facebook page that are connected to social justice. They are usually imperfect (as most metaphors ultimately are--love is, after all, nothing like a rose), but they serve to illustrate social justice points–and also how to set up a good extended metaphor.
Because writers never can have too much practice setting up good extended metaphors.
Most get a few likes and slip quietly into the night. But the most popular will get a fresh coat of paint and ascend to more permanent glory here at Writing About Writing.
