In the middle of the night, when you're ambiguously ethnic, like me, when you're brown, beige, mauve, siena, one of those lighter browns in the Crayola box. You have to be careful of the cops and robbers, because nobody's quite sure what you are, but everybody has assumptions.
But I can only write what the muse allows me to write. I cannot choose, I can only do what I am given, and I feel pleased when I feel close to concrete poetry - still.
