That's the rub... he doesn't really have time, and he doesn't really like to lunge anyway. She's frustrating for him because she just faces him and won't go... she's not real good at lunging and he isn't real good at teaching her to do it, because he doesn't really know himself. I think it'd be good for her to learn it and do it, he'd rather just ride her. I can take over and get her moving, but she just does the same thing when I give her back. Yesterday though, he got really mad at me when I was trying to yell instructions, so I said "direct that anger at the horse! get aggressive with her!" He did and that worked. It was funny.
If she got better trained at it, it'd probably make it easier for him to get the concepts to. Right now it's blind leading the blind.
