"But perhaps no behaviors are as frustrating to someone trying to elicit some degree of accountability from another as are the tactics of evasion and diversion.

A moving target is hard to hit. If you try to confront an issue head on, a person who wants to manipulate you will do their best to side-step the issue. Evading a matter of central concern is a great way not only to dodge responsibility, but also to keep the light of illumination from shining on the behavior needing attention."
