It was my 2nd lesson, and I was mounted on this absolutely brilliant ex-show-jumper. He was the first horse I'd ridden, ever, where I felt like part of a unit instead of a piggy-back passenger. Unfortunately, I squeezed him into a trot but when I went to *try* to post, I must have given him the Mystery Sign for cantering. I stuck on him like a tick for 2 trips round the ring until I realized 1) ex-jumper (like 5' fences!), 2) cantering, 3) already dished out one mis-cue, 4) jumps in middle of ring, and 5) no earthly idea what would be interpreted as a cue to head for one of the jumps. That was enough for me to un-freeze, lose my balance, and decide that I needed to Bail Out before something disastrous happened to the horse. The part of my plan where I needed to ditch the stirrups and reins went fine, but something went wrong with the rest, because 10 minutes later, people I have never seen in my life (EMTs and cops) are asking me if I know where I am (no), what happened (no), and what day/date/month/season of the year it is (no notion). The told me "YOU HAD AN ACCIDENT! YOU FELL OFF A HORSE!" and my response to this was to say "Wow! I ride horses? That is awesome! I didn't know I rode horses!"
They took me away in the ambulance - I was later informed I am the first person in the 20 year history of the stables to be carted away by ambulance from a fall. (we need a chest-thumpy sort of emoticon for this!)
I bought a new helmet and found a sticker that looked JUST like the horse I had to ditch off of (a beautiful chestnut warmblood, 16.2 hh) and put it on my new helmet. The instructor told me it was too bad I didn't get a discount, since I'd only gotten to wear the first helmet once. I told her I had something better than a discount...I had STATUS. Because, holy cow, every single person in the tack shop wanted to hear All About this fall, and then told me THEIR absolutely hair-raising stories.
Anyway, after this (breakthrough today) I decided it would be a good thing to ride 2x per week, so I get to have an extra lesson every week now. Next up: jumping! (not!...but at least I can entertain the idea that I might be able to do that at some point...)
