This week's challenge: haiku ficlets!
The haiku is a Japanese poetic form which is, most simply, three lines: the first five syllables, the second seven, and the third five. Further, however, the haiku contains seasonal words -- not necessarily just the names of the four seasons, but clues which give the time away (harvest, blossoms, snow, cicadas, for example). The focus is on sensory experience -- there is rarely, if ever, abstract language in a haiku.
The haiku ficlet has the same rules for content -- concrete sensory imagery rather than abstract references to emotions or concepts, seasonal clues. It's structured as three paragraphs: the first fifty words, the second seventy, and the third fifty.
