Okay, let's get rid of the stupid idea that lying is immoral first. Everything you do must be in your best interest, which means you must do whatever you can.

A lot of people don't understand how lies work properly and their stupid lies are very easy to spot. Most importantly, they don't sum up experience.

Rule 1: Your lie is unverifiable, which means that the other party has no way of knowing whether you are telling the truth or a lie. To do this, you need a few minutes or few days(Depends on the complexity of the situation) to prepare yourself. Pause for a few seconds before speaking and speak carefully.The most important thing is to know for sure if the other party is truly unverifiable.If the evidence is in your hands, destroy it!

Rule 2: You believe that what you are telling is not a lie, but the truth. Contradictory? Actually not! To do this, you must mentally accept that you are not lying, and you must be calm enough to pass the lie detector. Don't collapse under the pressure of the other party! When they can't verify the facts, they will look for a breakthrough in you!Remember, don't admit that you're lying unless they show conclusive evidence.

Rule 3: There are no logical errors. A fool once said she used the landline on the desk to call the police while her hands were tied behind her back by a robber.

Rule 4: Your lie must be a complete closed loop. This means you can't use open lies. As the old saying goes, "one lie needs many lies to make up for".
