Last Sunday, saddle goes on Milton preparatory to lunging. Milton leaves barn at Mach I, bucking like a rodeo bronc. Milton gets out to the ring. Stops. Looks around. Heads back to the barn, still bucking like a rodeo bronc. Enters barn at Mach 1. Spectators in barn unclear on how Milton plans to stop. Milton hits the brakes. Stands in front of us, puffing like a locomotive.
He’s athletic. He’s girthy.
Sigh.

He’s frisky! 😉
This one concise story tells so much of horse logic.
Would you rather have him lethargic? You claim to be black/white, on/off. Like dogs and cats, do horses reflect the owner?
