Figure out what kind of person I am currently dealing with. Respond to each type completely different: 1) Wise people listen, so talking to them works. 2) When dealing with foolish people, stop talking and set limits and consequences. 3) If the person is behaving evil, let lawyers and law enforcement deal with them.
Remember, 55% of the message is conveyed visually through body language and facial expressions, 38% is expressed vocally by my tempo, tone and inflections and only 7% verbally through my words. Before speaking, assure all 3V’s are congruent to avoid confusing the listener.
Sounds like you are on the right path of dealing with her.
