When you say to your boss can I have a pay rise? and he says no and comes out with the same bullshit as usual the company has not made so much money this year blah blah blah, and he says "No" what do you say in return, with a fake understanding face "Oh never mind I will ask again next year" what you are dying to say is "You Bastard". No, we also lie to ourselves daily I heard someone the other day say I don't drink much to someone else, when they live in the pub.
We also do it to our loved ones not me of course, I had a friend who would lie to her partner she would spend to much money on clothes and keep them in the boot of her car and get them out slowly so he wouldn't noticed. I found it hilarious at the time but, but not so much anymore it wasn't me honest, it wasn't.
I must admit when I was child I was the best liar in the world and I would be believed I was that good I was so convincing that I would get away with everything, except for my Parents who saw right through me, I did give it a good go though.
In conclusion I am convinced lying is in our D.NA we can't help ourselves, but as you get older you start to feel guilt, and it starts to fade, and we do it less. We are a planet of liars.
