A person cannot stop speaking lies. I might sound weird, but this is true. Just imagine, one fine day, the human brain (of all humans in this world) unlearns to lie. What would be the consequences?
You cannot bluff something to your wife when you go home late. If you were up to something and your wife did not like it, you will have a tussle. Tussle leads to a fight and that makes both of you unhappy.
One cannot lie to the traffic cop, regarding the registration of his vehicle. Finally, he/she will end up paying money.
Politicians cannot give promises. Since most of the promises are hypothetical and from imaginary world, they will have a tough time. I think, unlearning to lie will hit them the most.
Salesmen will have a nightmare. In my opinion, there is a 10% minimum average of lie in the selling strategy. They can say no more lies and their sales will be hit.
You can say no more lies to your manager regarding slipped schedules. When you give out the exact reasons for your slippage, like blogging, browsing, gossips etc., you stand the danger of losing your job.
Ultimately you can see, a person cannot stop speaking lies. Underlying premise is that, lies cannot be undone with, unless the circumstances which require you to lie are gone. So as long you have circumstances to lie, you cannot help but to speak lies. Since these circumstances are not solely created by us but by others, we cannot stop speaking lies unless others stop creating the circumstances. This is absolutely impossible!
