I’ve never had much tolerance for folks who blame the horse. Almost every time it happens, I find it hard not to want to point out how the rider’s personal short comings might be the problem.
Not surprisingly, it’s almost never the accomplished riders who look to blame their partner.
It could be a temperament issue or it could be that the more a rider learns, the more they realize how much more there still is to know.
The horse will always be your best teacher if you stay open to accepting his feedback for what it is…:-)
