When approaching a horse you have to ensure that you?

you must never walk quietly!! it will spook the horse and even cause it to buck or start kicking!!! You place both or one hand on the horses back and slowly and cautiously move your hand to were you want it! if you are waking behind the horse make sure you talk and let him/her know you are there!! you will know if the horse doesn't approve of what your doing by watching the ears if they are back that indicates that the horse is angry.and you should back away! if they are upright it's OK to proceed!
