@ Simone: ha ha ! indeed, yawn!
And remember, there is no naughty horse, only feedback and information for you so you can adjust your body in order to get the result you both want.
Now, when you leave, make sure you do a lot of transitions back and don't let the horses go chasing each other, keep it nice and calm. walk, and short slow trots. Keep it at that for now!
You are in excellent sensitive rider, trust your gut.
By the way, if I were you, I would not take lessons for a month or so. Just experiment a lot with what you've realised and it will start making even more sense.
If you get the need for instruction... maybe stick with Sandy for now.
You know, she knows what you want and what you need
And other then that, she is a fantastic trainer!
I would advise not to try any other trainer (for lessons, attending clinics as auditor is always a good idea) untill you are very confident about yourself and your horses and even more so, have a vivid idea of what YOU want out of this.
Then you will be able to add new imput from other trainers and filter out what you can not use and adapt what you can.
Advise from the heart from one who has been there, where you where (I know you can hardly believe it, but I too once cried on my horse!).
@ Donald...indeed... I can not see hills from where I live, and I have been longing this all my life. Apart from Ralph and my animals, that is the first thing I want to see when I go to bed and wake up!
