Anyway, what percipitates these are verrry clever and unpredictable moments, but every single one was when your guard was down and you THOUGHT you were having a lovely, relaxing walk on the buckle moment. But you weren’t.
Last one I (didn’t) rode, after a dressage work out, we went outside my trainer’s indoor to walk about the field and look at the new fences there built specially for him. Walking around the edge of the field, I remembered never to take him for granted, and started to feel him bouncing on his toes. In the field, 5 crows congregated on the ground. I had my leg on, had him in hand, started to make him work, which is his signal that I am not to be taken for granted. He stopped, and watched the crows fly up. He literally watched them go into the sky - head rising to watch. Then he cocked his head and looked around the field as if to say to himself “Hm. Anything else I can use?” Every indication of him going to pull a stunt, with malice aforethought. I made him move his legs. He dropped his shoulder and I stuck with him and hollered “Oh, no you don’t!” and turned him back on the path, moving him into a trot. Man, was he pissed - he threw his head up into my face, smack, and broke my nose, and my glasses flew off. Now he dropped the shoulder again, spun , and I was behind his movement because of my bloody nose, grabbing the oh shit strap, and he plunged, I came off the side, and he galloped into the barn, and stood waiting for me in the cross ties.
About once a year he tries this. Its better than before, used to be about once every few weeks. Its calculated, and evil, and to be honest, he hasn’t actually done it again since August 2013, but his trainer, leaser, agrees, its only because he believes she is un-dumpable. Were he ever to believe otherwise, he’d give it a go. Just who he is.
