Heck yeah!!! If my horse jumped at my level of skill ability right now in the hunter/jumper discipline- 9 out of 10 times I would either: fall on my butt, Toby would refuse, and I would probably still fall off, or any number of bad things may happen.
Horses don't (usually) respond to "Hi pretty pony! Will you plleeeeaaassseee w/t/c?!?!?!?!?!?!?!? I'll give you an extra special helping of carrots!" (I kinda learned that the hard way ;D)
Just because you rode a "bucking bronco" (in actuality it was a horse that was trotting and you fell off) when you were 12 years old doesn't mean that you can ride my crazy nutcase horse!!!! Well, you could, if you'd care to do the superman over my horse's head!!!
