I got to do lessons at the same time as my daughter --- that was the highlight of the week. It was really great doing it at the same time.
Dixie was an absolute dream while we were walking, she was listening to leg cues, and turning off of my leg before having to use the reins -- she kept her head low so her back wasn't hollowed out, everything was near perfect
... and then we trotted
She turned into a nightmare, she was running to the side, ignoring my legs, ignoring my reins, and I thought for sure I was going to fall off again (i so was not ready to fall off in front of my instructor)
She stopped the lesson, told me to get off, get my lunge line and lunge whip -- first she lunged the horse, then I lunged the horse, we ran her pretty good
Then she told me to get back on and trot .. so I did
At first there was some drifting and stubbornness -- but that gradually went away
She told me I need to try to spend some time with dixie every day -- even if it is only 30 minutes -- lunge her -- then tie her up for 2 hours before letting her go
She needs to learn that go means go, turn means turn, and she is going to work whenever I want -- and her drifting, and stubborness is only going to make things harder on her (plus it is safer for me to lunge her than risk falling off again when she is being a butt)
The tieing up is so the lesson can sink in and she learns that just because I am done riding, does not mean she goes back to doing whatever she wants.
