Heh, don’t feel too bad. I managed to fall off twice in about 3 minutes at a halt.
I was horseless at the time but taking a group lesson with my friends, riding the trainer’s 3 year old. I had been riding for 20 years, so knew my way around a horse. Or so I thought. Before the lesson started, trainer went to make a phone call, I proceeded to mount up on this 16.3 lovely girl (I was 5’3" then; before I shrunk an inch with age). I was in the center of the ring, adjusting my leathers, busy talking with my friends who were mounted and walking on the rail. Next thing I know I’m on the ground.
It was a HUGE buck from the stand still while I was leaning down fiddling. I climbed back on, didn’t manage to get my right foot into stirrup, another HUGE buck. Back on the ground.
Trainer arrived just as I was getting up. I told her what happened. She was like “OMGosh, she hasn’t been out of her stall for a week. Go get a lunge line.” (The farm’s pastures were closed that week in preparation for Horse Trials). I proceeded to lunge her, basically 5 minutes of non-stop running and bucking. Big sun-fishing types of bucks. I got back on and had a wonderful ride.
I went to work the next day, rather sore, and a non-horsey office mate, Ken, asked what happened. I explained. The day after that, I arrived at the office with the great news that I had bought a horse. He looked at me and asked “Not that one who dumped you. Twice. From a halt.” I happily affirmed the good news. To this day, 30 years later, Ken thinks that all horse people are nuts.
P.S. That mare was my heart horse. Feisty as the day is long and more full of life than any horse I’ve ever known. But we had a bond from the very beginning. Her name was Fiesta and her nickname on especially “enthusiastic” days was Feisty Fiesta. Tragically, I lost her as a 5 year old from complications after colic surgery. (Broke her right femur coming out of anesthesia). I can still cry thinking of her and all the years we didn’t have together.
