White lies play a very large role in our society.  They seem to permeate every crevice of relations between people.  Lies tell others that we are better than we actually are or more put together than we appear to be.  Some of the lies that tell are little ones to save someone's comfort or ideals.  Some of these falsely build our self image.  There are two categories of white lies also.  They are altruistic and Pareto lies.  The altruistic ones just benefit the one telling the lie.  The Pareto lies benefit both parties.  Often, we seem to tell lies that will help both of us.  You can read more into a study of white lies
