This from a well known psychologist on why people like you three are
chronic liars:
Lying is the number one reason that people lose trust.
The most common reason that people lie is to avoid confrontation.
Getting in trouble is never fun but lying to avoid it is always a
"band-aid" solution. When the truth comes out the confrontation is
guaranteed to be even more unpleasant than it would have been without
the lie. A lie compounds the problem, it doesn't solve it.
Another common reason people lie is to make themselves seem "better" or
more interesting. This sort of lying can be a sign of low self esteem,
problems at home, or depression.
Lies are like dominos - one lie can knock out whole relationships,
destroy entire aspects of your life or even limit your future in
unforeseeable ways.
Lies are a gamble. Every time you lie you gamble with being caught.
Lies have a way of getting out and coming back to haunt you.
The worst lies are the ones you tell yourself. When you lie to others
you are also lying to yourself.
Chronic lying can signal a psychiatric or social disorder. If you find
yourself "lying for no reason" or to cover up behavior that you know is
harmful consider seeking professional help.
Lies can damage your self image and cause inner conflicts (like
dissonance) that drastically change the way you view, and act upon, the
world and other people.

Please note the last one, that chronic lying can signal a psychiatric
or social disorder.
