a haiku, aside from the syllable strucutre, captures a fleeting moment that tends to focus on simple, sensory imagery. haiku evoke sudden insight or emotion, and they frequently juxtpose two images with a cutting word.
children frolick in
mud and dirt and dismay--
alone in song, together interrupeted
sun hides--
blanketed by the moon
and casting their hue
toes stretch out straight
but stop just short of the wall
yawns of feet tired of shoes
