I suppose it is possible to live a completely honest life but it is quite likely that that person will have a lot of enemies and few friends.
There is a difference between telling a little white lie to save either yourself or a loved one some embarrassment or hurt and telling blatant lies to advance your cause.
When people lie to benefit from it either monetarily or politically, it is a very serious issue. And these people can never be called normal people.
Whereas if a person tells little fibs or white lies, without a thought of gain, it is often excusable. But having said that, some people are mostly honest in giving their opinions without wrapping them in cotton wool and they are the most honest kind of people around. People who know these “honest Abes” will seldom ask the rhetorical questions which can have only one answer.
My conclusion is that either one can be a normal, polite fibber with friends or a totally honest person who has very few staunch friends who value honesty above politeness. And we aren’t talking about pathological liars!
