So your sweetie was "working late" and you want to know if he's telling you the truth? According to a "Human Lie Detector", it's easy to catch someone in a lie, because their body subconsciously gives them away!
Here’s the list of things to watch for:
A change in the voice’s pitch.
A change in the rate of speech.
A sudden increase in the number of “ums” and “ahs.”
A change in eye contact. Normally, one makes eye contact one-quarter to one-half of the time. If suddenly, at the convenient moment to lie, he’s staring at you or looking away, beware.
Turning his body away from you, even if just slightly. (Or placing objects in front of self in order to create a barrier of sorts – this could be paper, coffee cups, sugar dispensers, etc.)
Suddenly being able to see the white on the top and bottom of a person’s eyes, not just the sides.
A hand reaching, even if momentarily, to cover part of the face, especially the mouth.
