Someone preoccupied by their falsehoods may tap or wiggle their feet a lot. One's feet reveal the most.
If a person's foot points away suddenly, they may be fleeing or lying. Their feet contradict their words.
Lies can cause two more appearance changes. They may wipe their head with a cloth.
Another is that they worry with and brush long hair to the side. This distracts people from their falsehoods.
As the windows to the soul, eyes may reveal deception. Eye movement can "simply" reveal a liar.
If they avoid eye contact, they realise they're lying and are decreasing their guilt.
This makes people cross their arms and legs, making them look smaller and more uncomfortable. Confident, truthful people have open body postures.
Each person's main body language symptom of lying is unique.
If someone's body language differs from others, it's crucial to examine. Someone lying should modify their conduct.
