This girl, who was really a mermaid, only no one could tell on account of the legs, ran so fast that she went right off the edge of the world.
Swoosh. Just like that.
First she fell with her legs straight, like a metal rod, with her arms crossed over her chest.
Then she fell sideways, rocking like falling feathers, only faster.
Then she got bored and fell like a sack full of mud.
Finally she pulled her legs up to her chest, locked her arms around them and got very quiet and very small. She felt like a ball, or a robin’s egg. She felt like a snail shell with the snail inside.
Then she kicked off the bottom and swam up.
