Crazy is when your actions have negative consequences for others, and you don’t care and/or notice.
That’s the best definition I can come up with.
Examples:
My mother is crazy. She thinks the world “owes” her something, her children are property meant to be controlled and intended for her service, and goes out of her way to force her personal misery on the very people she is supposed to care for and protect. She cries – not to express sadness, but to cause the people around her to feel guilty for their own actions or to feel sorry for her. She becomes violent when angry and throws things or chokes people that can’t fight back for whatever reason.
My husband’s mother is crazy. She is stubborn to the point of dangerous. If a door doesn’t “shut right”, she will find a butter knife and take the entire door frame apart trying to “fix it”. She will then “fix” the doors on the car, the door on the shed, the handles on the kitchen faucet, and the shelves in the refrigerator. She steals, lies, and spreads harmful rumours, and uses the Bible to defend herself. She hasn’t bothered to learn my name in six years because “Satan has authored this relationship”. When she becomes angry, she shouts profanity and vulgar phrases.
