A Writing Prompt: The Stray's Story

Probably everyone (and especially those who live in rural areas) has at least some experience with stray (kittens, dogs, parakeets, etc.). My family is no exception. From a pure-bred blue whippet valued at $2000 to a litter of rottweiler puppies and a sampling of everything in between, we thought we'd seen it all.

Until the stray horse showed up last week.

So right there you have a writing prompt. You have a relatively normal occurrence (a stray showing up) with enough twist to make it interesting (strays don't usually come in the form of horses) and an unanswered question (Where did she come from? Why would anyone dump such a sweet little mare?)

Put your imagination to work! Spin the story behind that stray (horse, dog, cat, iguana) that mysteriously showed up at your house. What is the stray's story?
