some people would say I am bossy, I like to think that I just have better ideas!
When it comes to the horse world I have been around these animals for well over 60 years - most of them as a professional. My experience in handling the difficult animals is great. I love a challenge and turning a 'bad' animal around. It was my forte.
So I. All the time I have been with these beasts the biggest change I have found is that whereas people went to a riding school to learn to ride and learned on a great varieties of animals, now more and more people have a few lessons, get their own horse and forget the lessons. These are the ones who, now they are older class themselves as experienced. They are going out to help other newbies and so the cycle will continue with each generation looking more and more into the faults of the horse and not to the handler/rider.
They do not mean harm it is just ignorance. Whoever said "Ignorance is bliss" wasn't a horse.
If I see something and I will use the OPs video of her riding, the first thing I would have said, even if I was just walking past, I wouldn't be able to stop myself, would be for her to stop and we put the saddle on further forward.
I would probably say, "Excuse me my dear, your saddle seems to be a little far back, shall we move it into its proper place?" Rarely would a novice person take offence at this whereas if I were to yell out, "Hey, your saddle is in the wrong place don't you know?" Offence could well be taken or it would certainly upset the novice youngster.
From that I would watch, I would offer advice, explain what and why, knowing that the rider was a novice but eager to learn. Knowing me it would turn into a sort of lesson. Just can't help myself, I enjoy helping people.
There is the old saying, "Those that can - do. Those that can't - teach."
