Nina finally showed her old colors and tried a little rearing. It wasn't much, fairly half hearted but still disappointing that she had to try it. I was expecting it and hoping not to see this behavior at the same time.
On the good side she did manage to get her brain working again and walk forward quietly after.
I suspect we are in for a rough patch and she will be testing to see if she can get me to fight with her. My job will be to get her thinking about working without feeding into her temper tantrum.
