In one sentence, describe what the following article is about:

When you communicate with your horse, it is important to remain calm. If you don't come in knowing what you want to do, you will likely fall back on feelings and instincts. This will make you more likely to panic or overreact to a horse's actions, rather than remaining calm and in control. When you come near a horse, you want to make sure he is willing to talk to you. If the horse wants to talk to you, he will turn his head or front toward your, lick his lips, and soften his eyes. Once you get this signal, you can approach the horse slowly and start communicating further. Your horse may do the opposite, turning his head away from you, walking away, or even ignoring you. If the horse isn't interested in letting you in, he won't be responsive to what you say. Horses have monocular vision, meaning they can't see directly in front of their noses. Make sure you walk toward a horse from the side so he can see you clearly. Never approach a horse from behind. Horses can't see in that direction, and you are at risk of getting kicked if they get spooked. Make sure your horse recognizes that you are the leader of his herd. If he doesn't recognize you that way, he won't listen to what you are saying. If your horse doesn't seem to be showing proper respect, make him move his feet. Pushing on his shoulder or hip should do well on most occasions. If you need a little more power, you can poke him with the handle end of a crop. Just make sure you stand in the same place when you do this, and don't shuffle your feet. A horse that doesn't respect you will rub his head on you, nip to get your attention, or walk in front of you when you are trying to lead him. These are not behaviors he would show to a dominant leader of his herd. Horses are prey animals, meaning that in the wild they are hunted by others, and your horse considers you a predator. This means he will consider any outsider to be a threat, including you. Learn to approach the horses calmly so they regard you as someone walking through the herd rather than a potential predator.
Plan what you are going to say. Watch for an inviting body position. Approach the horse from the front side. Become the leader. Approach the horse calmly.
