How can you tell if a person lies? Is it a matter of doing something unnecessary while talking to somebody? Or just simply do not entertain the idea that will lead you to lie? Certain things that you can find out if the people are lying. It’s when somebody cannot look at you eye to eye. When his eyes speaks louder than his voice. Meaning when he is looking onto something else and not to the person he’s talking to. It will become obvious when he seemed to be directed with any other things by looking to something else that will caught up your attention. And once it happened your focus is not about the topic you are talking to but of somebody else. So that clearly means he is hiding something and the tendency is to lie. And if he cannot get away on lying he will simply change the topic
