This story is amazing! I have no horse of my own, but I was close enough to a filly to think of her as "my horse" (see the story REDDY on this page). I certainly wish something similar to your story would happen to me; it would be wonderful if it was just a MINIATURE horse I was able to call my own!
REDDY is not the only story I have posted on this page. The other one is called VICE VERSA, and it is closer to the top of the page. REDDY is near the bottom.
