I think my first fall was when I was about...Oh, I don't know, 9? Something like that. Anyway, it was one of my first lessons with a new riding teacher and I was on an Arab gelding. I think we were trotting around the ring and it was windy outside, and suddenly the tree next to the arena scratched the roof (it's an open/covered arena, not closed in) and he went off like a rocket. I managed to stay with him in the turn, but then he swerved again and I flew off over his head. I think I landed on my bum, so I wasn't too hurt, but I cried, because it scared the heck out of me. xD I'd never experienced anything like that before. Got right back up, of course, and I forgave him. :) He was a good little riding pony.
