Well, it's a given, Hunter is a right-brain extrovert who has learned to trust one person - me. He's really a fine horse and I love him a lot, but he will still stand on his hind legs in cross ties if something scares or upsets him.
Tosca, probably closer to a left-brain introvert. No wonder I'm having trouble working with her. She is at the opposite end of reactions from the TWH. No one would ever refer to him as "sweet", which is how I think of her. He's more needy. Nancy
