I love it when people understand that horses don't act perfect for a new rider, they just don't. I had girl come look at my horse who needs an experienced rider, I told her right away, he needs experienced riders, she said she's ridden for over ten years. She hopped on and the first thing she did was kick. Then he started going at fast walk she was pulling the reins to slow him and then kicking at the same time to keep him going, neither of which he liked. I'm surprised he didn't rear. My horse only needs gentle tapping on the reins and thigh pressure, period and she was really wailing on him. I had to stop her and tell her to get off, because he was standing there, ears pinned mouth gaping just dealing with it. She complained that he didn't know anything and kept ignoring her. :roll: The guy she was with said she has only ridden twice before and apologized for her.
Watch out for that kind of stuff and be gusty enough to say "Hey! She doesn't like that," or "Watch your hands, your pulling too much." because sometimes they don't realize it.
