ProudLao mentioned about being "scared". It's natural to be apprehensive as it's a big live animal. Since it's a live animal, always build the relationship on trust. I've never met the horse I rode recently but I did my best to earned her trust but talking to her in a calm voice while gently stroking her hair in the neck and shoulder areas following the directions of the hair. Don't stroke against the hair directions because it can be uncomfortable for horses.
