Lying to cover a situation which would be better served by the truth. Taken from the habits of Bill Clinton, 42nd President of the United States of America, and the only President to be officially sanctioned by the Supreme Court of the United States for lying under oath.
Often the behavior of small children and others not used to the truth.
Quit Clintoning, Joe. I know you had nothing to do with it. You don't have to blame space aliens.
