When a person who has been told a white lie discovers the truth, they may change their view of the liar to the extent that the relationship is changed.
If they were seeking honesty, they may view the liar negatively, being angry at the evaluation of themselves as unable to accept the truth, or seeing the liar as a coward whose purpose is more driven by self-protection.
If they would have found the truth difficult, then they may appreciate the white lie as being based in concern for them.
A possibly difficult conversation may then follow, in which the truth and reasons for the white lie are discussed. Alternatively, the person lied to may perpetuate the lie or tell white lies of their own to avoid further distress or harm.
