He did decide he was going to have an OMFG BOLT moment and I think he bucked somewhere in there because I fell forwards onto his neck and nearllyyyy came off. But I'm so proud of how I handled it, even though it scared the crap out of me I stayed calm (I am your typical teenager, I get emotional at the smallest thing, but I'm getting there, and by the time my foal is ready to be started I'll be nearly 20). I was sure I was going to come off and hurt myself badly again. But I didn't, and the ride home was fun and constructive, so I consider it to have been a good ride.
Two lessons with my new coach have made SO much difference, I'm going to stick with him on a long-term basis, and I think years riding under him will make me a brilliant rider not just a 'pretty good' rider. I have a great position with a stable lower leg but (I think it's my confidence more than anything else) I've not really been asking him for forward, and he's a horse you need to RIDE so he's really been showing up my flaws.
I should get Mum to video me every lesson so I can actually see what's going on. It feels awesome, he has SO much power I never really thought he had and my amazing coach is helping me tap into that. My amazing coach says I need bigger knee rolls in my saddle
