What does it mean when certain folk are hypercritical? Well, either you’re doing something wrong and need correcting; or they are not going to let you be a normal, fallible human being. Now, if you don’t have time and have to beat the clock then you have a friend or fiend who will be your task master. Lucky you.
Some people see only the good in themselves and see only bad in others. They see the flaws of others a mile away but can’t see the ugliness that they do. Everyone else sees their ugly habits or low character but they sure as heck don’t. But they can see yours.
These people have the limited value of the lightening that illuminates the silhouette of the elephant in a pitch black room. Maybe you didn’t want to know X but there it is. Now deal with it. And if you can deal with that you can solve how to keep your boundaries firm when living with or in close proximity with hypercritical persons. Feel free to tell them the truth about themselves in a diplomatic way. And please remember that good, friendly fences make good neighbors.
