I am not good in telling lies. But my trustworthiness is such that even when I tell lies for reason whatsoever, every body takes it as truth. So my lies are literally limited and used only for genuine reasons. I think more than the artistry, it is the standing of the person that makes his lies escaping any scrutiny.

It requires very good memory and a creative mind to tell lies. Lies are difficult to remember and one who does not have good memory can not be good at lying. Since I have dementia and a failing memory I am not good at lying.
