Some people almost seem proud of their horse's bad manners. Like it indicates "spirit," or some such nonsense.
I groomed a few games a couple years ago for a polo player whose horses were ill-mannered. They quickly became well behaved for me. The first day. But when the player would handle them they acted all screwy. Once as he was leading a mare while she was bouncing up on her hind legs, he said "They can always tell when I'm around!" A nearby teammate muttered "yeah, and that you're a pushover."
So true, as I have seen that. It is not so much the bad manners, but the pride they get in showing that they can ride such a horse.
How do I know that? Well, color me guilty! I was a teenager, and did not know any better
Once that stud stopped rearing and going over backwards, that I posted about before, he would still take off at full gallop, soon as my left foot was in the stirrup. One of the workers, we had , in the summer, for the tobacco fields, tried to ride him, but could not get on, for the reason mentioned\
I was 17 and that guy was kinda cute, so getting on the rest of the way, while my horse was in full gallop, was 'false pride' on my part.
What can I say, I had no mentors, and that is the way I saw some of my favorite western heros mount!
