I particularly like the sense of realism in the timing in this haiku, Robert.
There is the brief, sudden opening of a lightening flash, then a sense of a pause before the second line, and in that pause the poet appears to be puzzling over the fragmented visual image of what was just illuminated. Then it is all pieced together, and it is bizarre and real and wonderful. What an unforgettable image – rain drops on the spines of a hedgehog (and we don't even have hedgehogs in Australia) – all glimpsed in a lightning flash. Indeed, if I were a Zen devotee, I might even say you have captured a moment of satori.
A camera might capture an image of such an animal in a flash photo, but your haiku reveals the animal, and the observer, and the flash, in a transcendental 3 line moment.
Wonderful poetry, Robert. Thank you for sharing it with us.
