Short, sweet, and immediately applicable. She supports her statements with examples of interactions we have all experienced before. She makes step one of boundaries very clear, which is to explicitly state your own boundaries. Boundaries are important because they invoke a challenge and manipulators do not like a challenge. I personally choose to preference this with manipulators, that I have seen, that do like a challenge. She stated that a good solution to this is for you to be a good judge and realize When your boundary has been crossed. Nonetheless, very good book to repel unnecessary people from your life.
