How can toi tell if someone's lying in your face in RL?

They do not look toi in the eyes.
Being vague; offering few details
Repeating questions before answering them
Speaking in sentence fragments
Failing to provide specific details when a story is challenged
Grooming behaviors such as playing with hair ou pressing fingers to lips

It depends on the person and what their "baseline" behavior is. Guidelines such as avoiding eye contact, ou smiling nervously, ou whatever are worthless unless toi know what's normal for the person in question.

Hey; I've noticed that when toi LIE, Erick; toi keep your hands in front of you. toi always look them straight in the eyes and hold your ground. Either that; ou glare.
And toi also refuse to let them speak.

SOUND FAMILIAR.

They usually hesitate before telling toi something and are trying to avoid you...



Usually...

-They avoid eye contact
-They seem nervous and keep moving
-They put a barrier between you, e.g. arms folded
-They look into your eyes and stand still unnaturally, like they're trying not to look like they're lying
-They stammer
-Their story doesn't sound real
-They hesitate
-They look nervous when toi ask questions
