I've had those kind before. I had to give up on two geldings, they were ok on the ground but dangerous demons to ride. I sold them with full disclosure to some cowboys that thought I was "female" and didn't know what I was doing. They sure regretted their purchase, but I told them. snicker, snicker.
I have a mare that was badly abused, it took much patience and time to gain even a tiny bit of trust. She is 31 years old and still shies away. It took 12 years before she asked for attention. She moves away from me, but will come to me if I have a brush in my hand LOL. I know the issues I can deal with and I also know when to cut my losses and move on. I am looking forward to getting to know this little mare. And thanks for the "hearts".
