Yet another red flag is a universal disrespect for other people‘s privacy, boundaries. This is a result of his viewing people as mere objects there for the narcissist‘s sake and to serve his needs.
For example, your property line affects him like waving a red flag affects a bull. He must violate it and make what‘s your territory his territory. So, he parks on your lawn, ties his big mean dog out at the edge of his property to use yours (and menace you with Rover). He reacts to your claim of ownership as though you are stealing from him. Nothing short of a big fence will stop him from making your property his. And then he‘ll probably ram it with his truck if he thinks you‘ll be intimidated by that.
In other words, he is incapable of “distinguishing between mine and thine.”
Which is why a narcissist sticks his nose into everything, for he considers your business his business. He feels it incumbent on him to bestow judgment every single thing people think, say, do, wear or feel. His disapproval (or the threat of it) is a stick this control freak with a God Complex herds people with. So, he presumptuously makes other people‘s choices for them. Often to ridiculous extremes, such as telling people how to wear their hair, what clothes to wear, where to buy things and what brands to buy, what chair to sit in, what end to start on, which route to take, and so on. You can tell he‘s doing it just to do it, because he makes people change their choice to comply with his wishes. In fact, if the same person is doing what he said to do the last time, the narcissist tells her to do it differently this time.
In short, a narcissist views others as objects on a chess board, or tools, robots, the executioners of his will. One I know of, a private school principal, demonstrates the desperate compulsion narcissists have to control people. He is said to have nearly driven almost a thousand people to justifiable homicide by blasting over an hour‘s worth of nonstop orders over a blaring squawk box about what to do in an annual Christmas celebration that everybody had carried off without instructions for decades. Nobody could walk into a room and sit down without this clown telling them to sit somewhere else.
