ok, a LOT of people should not be allowed near a horse.
While I was riding today a woman riding in the arena trotted up behind me, so close that when Nina swished her tail it hit the other horse in the face.
Instead of telling her to back the hell off I was nice and just said "this horse might kick."
Her response was...."oh, that's ok, this one will just kick back"
You think she was being a smart ass, don't you? Nope, she was quite friendly and chatty about her lack of ability to steer her horse and her opinion that as long as both horses kicked at each other everything was ok.
I am going to stop trying to be polite, I swear it.
