My first fall was in a lesson. I hadn't been cantering for long and so I wasn't especially good at it lol Well anyway, I was cantering the pony around when he shied and I fell off. I wasn't hurt though and I got straight back on. I think my instructor was more scared than me!
The 'good' thing about falling off (not that its good!) is that it usually happens so fast you don't have time to be scared. By the time you realise your falling, you've already hit the ground! Sometimes you fall slower like if you try to grab onto the horse and stop yourself from falling. These are the falls that scared me the most because I can remember the most about them. Plus, you can tend to land closer to the horse's legs and are more likely to get stepped on if you try to grab on.
Generally, falls don't do much more damage than a sore muscles and bruises the next day. I've fallen off lots and lots of times but the worst that's happened to me was a fractured arm (but it was a minor fracture).
When I bestride him, I soar, I am a hawk: he trots the air; the earth sings when he touches it; the basest horn of his hoof is more musical than the pipe of Hermes. ~William Shakespeare
