I remember what I was doing the moment it happened.
I was riding my horse across the neighbor's pasture. The gelding was busy trying to snatch a bite of grass and I was trying to keep his mind off the lush green blades teasing his palate. Unexpectedly, the gelding stopped in his tracks and looked skyward. Forgotten were the long blades brushing against his belly. Perplexed, I sat back to observe the horse. He was not afraid or getting ready to bolt. He was listening to a voice I could not hear.
Ears forward, nose tilted toward the cloud dotted sky, I saw the horse's lower eyelids squint in concentration. His amber eyes scanned the sky. All the insects were suddenly quiet. I remember looking at a grasshopper crawling across the horse's mane and how she stopped. The mockingbird following us closed his beak and looked upward from the branch of a nearby shrub.
I remember the utter silence around me as my horse gazed at the sky. A few minutes later his nostrils fluttered a soft sound. He adjusted his head so he could look at me with one eye and continue to watch the sky with the other. His right ear turned to me. His left he kept aimed at the sky.
I stroked his mane and murmured we were okay.
I did not realize how wrong I was.
I will never forget how my horse knew before I did.
