Here are some very wise words about Rosso, the naughty horse, from my trainer that I love and trust and have known since I was 18 yrs old.
I know you are bugged about Rosso. Just chill. It will be fine; seriously. Honestly, any one of our horses has the capability to dump us on our ass at any given moment.
When he really understands that dumping you is a very BAD option he will stop. He is not stupid or mean.
No snowballing, bad voodoo and greegree.
