A Capacity for Self Deception

It seems that everyone in my family has a profound capacity for self deception. They also have dangerous and excessive amounts of ego and false pride in their own abilities. They then proceed to channel their hostile emotions, inadequacies and short comes on. It is always a bid to pump themselves up and to tear you down. Which at times can be ridiculous to the point of stupidy. Where it will end I do not know. But I know I cannot live with it any longer
