Note the white horse with dark patch on his face in stall on left is agitated. She lets big white horse out at 7:48:11, he leaves barn and goes into pasture. She lets dark colored horse out at 7:48:30 but she turns the wrong way and goes further into the barn. White horse comes back in and they both go to far end of barn. Dark horse turns around away from white horse and goes into full gallop followed by white horse. White horse deliberately looks at woman, takes aim, and delivers an accurate side kick at about 7:48:44. Although the kick made contact, the woman was not hurt.
By the way, that’s not a whip, it’s a Savvy stick; quite different than a whip. It’s basically a stick with a string on the end used as a body language prop.
