Answer 2

Hola

So here's your answer -

When you are talking with someone and you know they are lying to you, you notice they laugh. So that's just a sign that they are lying and they are trying to prove that everything's just alright and they often try to hide the lie by laughing. That's just an immediate action when a person is lying to you.

Hope it helps !
