I've falled off 3 times. I'll give a little story behind them all :)
I was 8 and was taking lessons. I was riding this horse Thunder and he was terrified of water. So we were walking or trotting and there was a puddle coming up. I wanted him to go to the rail, but he had another plan. He went left, and I went right, right into the puddle of mud.
The second time I fell I off, I was riding this pony named Purdy, and we were doing a little jump. For some reason she was afraid of the jump (even though we had just jumped it) and she went right and I went even further right and fell.
The last time I fell off, I was riding my fiance's gelding, Gem and he, out of the blue, did a huge buck, and I slowly slide off. I caught that one on camera (well most of it)
There might have been a fall between purdy and Gem, but I can't remember
