Proper protocol for gentlemen describing ladies who have incidentally ‘fallen off horses’

I made the error of asking a lady friend, “How is your recovering going from falling off that horse?”

This triggered her quick response, “I didn’t fall off the horse; he threw me!”

Boy Howdie, was this the wrong thing for me to have said!

She temporarily quashed the kind concern in my voice, however, I’m improving slightly every day and feel like I will soon straighten up and ride right again into the sunset with revised comments like, “How is your recovering going dear, from that horse you fell off, which threw you?”
