Anyone can lie.
Gotta tell you, I have trouble outright lying; I'm far more apt to "lie by omission" if I lie at all. It's far easier for me to allow someone to believe something that isn't quite true or just not tell someone something that might change their perspective, rather than saying something I know to be false. I usually did that, when I did it, out of a desire to not be controlled by someone else if they had too much information, or out of a desire to not be dragged into needless (in my mind) conflict.
It's hard to actively spin mistruth if a focus in your life is working with nuanced truth -- wanting to call everything exactly what it is, so that you can better clarify them and know what the big picture looks like.
