Absolutely. Lying and bullshitting comes naturally to them, and it makes sense as it can be seen as sort of a survival mechanism. I was extremely honest as a kid, and I almost never lied as I failed miserably whenever I did. When I got into my teen years and became more rebellious, that's when I started lying more, and at first I was terrible at it, but through time and practice I eventually improved my technique. As much as people don't like to admit it, lying can be a useful skill to know, and like I said earlier on, it can be seen as sort of a survival mechanism.
I'm still an honest person, most of the time, but I try not to let my honesty get the better of me.
