Funny how when you detach from the MLC storm that it hits someone else who is in its path.
To be very fair to my wife, OP, this is more about her older sister's issues. My wife grew up in fear of her sister. When they were growing up SIL chased my wife around the house with an unloaded shotgun telling her she was going to kill her (wife didn't know the gun was unloaded). On another occasion SIL stabbed my wife with a pencil and deliberately broke it off and told my wife that she was going to die of lead poisoning. My wife still has that piece of lead stuck in her shoulder to this day.
I guess it's fairly obvious that SIL is one of my wife's childhood issues.
