I recently tried to make Molly go up a bank she didn't want to go. It was very muddy but also very short and not too steep. She'd handled longer, steeper banks with no trouble. She hesitated, but I pushed her hard and she really, really tried. The mud must've been too much, because she couldn't make it. She slid backwards and ended up lying in the little creek with me still on her. She just turned her head and looked at me, not even upset, just a look that said, "Are you going to get off so I can get up?" Once I was off her back, she made it up the bank, that's when I realized how deep the mud was.
We all make mistakes and it's amazing that things don't turn out worse than they do sometimes. I'm a lot older than Brighteyes but still a pretty green rider, and it takes time and experience to learn to trust your horse. Brighteyes is right, sometimes horses get upset over things that are perfectly harmless, and you can't always let them decide where and when they want to go. In hindsight I realize that when she hesitated, I should've taken a closer look to see really how deep the mud was. So, it's a lesson learned and we're both okay. And I learned another lesson about muddy trails and when to trust Molly's judgment.
Glad you're both okay!
