It's the horses fault!

The way I read the description it sounds like she is blaming the horse for her jumping him badly. The horse isn't a good jumper in the video but falling behind as much as she did probably didn't help him much:

This is another horse that came to the dealer worked for, he cant half jump either. This is me just having a little play on him. I had previously fell off a horse jumping and lost my confidence, harry brought quite bit of that back for me..
