The Giant girl knitting on the mountainside cast a shadow over the village church. With each row she knitted, a villager died. When a posse climbed up to beg her to stop, she just giggled.
A boy, inspired by his puppy, suggested they build a huge ball of clay and cover it with glass panes. Once the villagers had pushed the ball up the mountain, they let it roll down past the Giant. The giggling girl dropped her knitting and followed the shiny toy to the next valley.
Today the clever boy is mayor, and knitting is considered bad luck.
Author’s note: Folktale style works particularly well in very short form, I think, since such stories often strip life-altering adventure down to its most essential elements.
