Did you know that a liar can only be discovered through a single question? Moreover, they will not understand anything you are raising a "trap" to unmask.
This mechanism is well known in the field of psychology and consists of a false statement that you must tell the suspect. If they accept and agree with you, they are lying. Otherwise, if you find that they are opposed to you, they are right. Just something; try not to repeat this technique often as others may notice and discover you.
You can rarely apply it when you feel that something is going wrong with someone. Try to keep the tone and posture you had, as body language can betray you at any moment.
For example, let's say you're talking to your sister's boyfriend and he tells you he was invited to Harry and Meghan's wedding. You suddenly ask her how big the chocolate cake was (while you know full well that the cake she chose was vanilla white and decorated with flowers). If he tells you the chocolate cake was a miracle, congratulations. Have a cheat in front of you.
Accusing someone of telling them that you are lying can affect your relationship with them. Moreover, your doubts may be wrong. In the above case, if you were to tell your sister's boyfriend that you were "lying," the latter would be hot, and the boyfriend would be offended.
So be diligent and discover stylish liars!
