No important relationship survives if trust is totally lost.

In some instances, you may care so much about the person who has hurt you, or be so unable to be angry with him (or with anyone), that you rationalize his hurtful acts by finding some basis in your own actions for his hurtful behavior; you then feel guilty rather than angry. Put in other terms, you become angry with yourself rather than with the one who hurt you.

A broken promise is not a lie.

Lying is a deliberate choice to mislead a target without giving any notification of the intent to do so. There are two major forms of lying: concealment, leaving out true information; and falsification, or presenting false information as if it were true.

MOST LIES succeed because no one goes through the work to figure out how to catch them.
