Answer:
The eyes: Someone who is lying might stare or look away at a crucial moment, says Glass — a possible sign they're moving their eyes around as they try to think about what to say next. The research conducted by Geiselman at UCLA corroborated this, finding that people sometimes look away briefly when lying.
if you know that she/he is lying, tell them that you're in a place right now where you might be able move on, even if there is more that you don't know. But also tell them that this might not be the case if more lies come to light later on. But don't just say, “Is there anything else you'd like to tell me?” This will likely be met with silence.
