One thing that really gets my hackles up, and this isn't directed at you OP, except that your one comment brought up the topic, is the "jump on the abuse bandwagon" state of mind that seems so common these days. SO many people, (I see it here on the forum almost daily) the second they have an issue, want to blame it on "maybe Fluffy was abused and that's why she doesn't like so and so". 99% of the time, Fluffy just doesn't respect you enough to behave or like whatever you are asking. It has nothing to do with abuse. Horses have minds of their own. They do not have to suffer abuse in order to dislike something.
