I honestly kind of just figured that her charging was more that she didn't know what I wanted than that she was being aggressive. Her ears weren't back at all. They were pricked toward me when she came toward me.
Truthfully, I much prefer a mildly aggressive horse because, normally, a couple of hard corrections and they stop, with the exception of the really aggressive ones that are truly out for blood. On the other hand, the "friendly" ones, you almost have to just terrorize them from the ground to get them out of your shirt pocket in a moment of panic.
That's wonderful news about your ankle, I am so glad that it's not broken. I have found, too, that the faster you get back to trying to use the injured extremity like normal, the faster they heal up.
