Symptoms of lying

People who are lying often cannot look directly at you, but look off to the side. Sometimes they may blush. They often feel pressure to speak, so if you remain silent, they will blurt things out and keep chattering away. Body language often gives away a liar also. They may lean away from you, or cross their arms in front of them, or fidget. Basically, any behavior that is different from the way they normally act could be an indication that they are lying. Of course, there could be other, perfectly logical reasons for this and they might be telling the truth.
