What are the signs, like body language or facial expressions, that someone is lying?

Answer by  falsetto (62)

Small facial movements, especially by the eyes are indicators of lying. Not being able to look at a person or tightening muscles can indicate discomfort and lying.

It can be very easy to tell if somebody is lying. If they won't look you in the eyes that is a sign.
