Teacher wants me to return lesson horse to tie up and take off tack.. Horse is spookish etc and I;m told to avoid umbrella. I think I should take another path, but was supposed to just squeeze away from umbrella. I take another path and when I want to go left. Horse wants to go rt bec his pen is there.. things get tense and horse is moving backwards.. teacher watching all.. she starts screaming at me that I must lean back.. of course I.m leaning foward bec I'm worried about him trying to toss me.. should I have leaned back? Teacher said horse might have been wanting to lay down?? Who knows? Am I supposedt to lean back to avoid a toss? I guess if a horse does rear up. Don't you eventually want to lean in and hold on?
