2. Another representative of the aggressive environment, in case of disobedience to his will, begins to shower him with threats.
3. The next type is always right and never makes mistakes. If you have one in your circle, beware of making a mistake or being inaccurate in his presence.
4. There is another representative who prefers to keep everything under his control. These are cunning people for whom it is not difficult to deceive their neighbor.
Caring and rags
1. The direct opposite of the first type is someone who needs constant comfort and support.
2. The manipulator may openly ask for help, but at the same time not notice, or pretend not to notice, how he puts others in a difficult situation with his requests.
3. The most incredible representative is the one who surrounds you with care and attention, always helps and supports, but does this with one single goal - to make you obligated to him.
4. And another benefactor will support you, even if you seemed wrong.
Knowing about these personality types will help you defend your boundaries in time and avoid bitter disappointment.
