I've been shopping around for horses and this past Monday, I foolishly got on a OTTB that hadn't been ridden in about a month. The seller (the owner's mom) did not ride the horse nor did she really want to be there. Needless to say, the test ride didn't go well, but I kept my seat even with bunny hops and wasn't really rattled....or so I thought.
After test riding this weekend, I went back to my trainer for my first lesson in over a month (I got an earful from my trainer on that so don't bother), but the lesson was pretty much a disaster. I was on a new horse and I could not get the fear from Monday out of my system. I was squeezing with my legs and hanging in her mouth. It was bad! But I kept my seat. My trainer got me off and rode the horse then got me back on kept the horse in hand and got me calmed down. I was rightly rattled.
I guess I just need to hear how you all deal with these situations, etc.
