I see riders fall off on the right side Of the horse. Why do I fall off on the Left? I jump. Is it the length of my stirrups?
My favorite to say is that I had some "unplanned flying lessons" and usually end up laughing about it. Sometimes I'll make a reference to the musical Wicked and say that "I was trying to defy gravity, but the gravity won".
When you 'achieve' your fall of the year, you qualify for 'the Autumn Club' and get a red maple leaf lapel pin (a tiny one!).
