Sounds a lot like my mother.
I had a boss that did that ALL the time
your that someone is really mad or mental sick...:O
All I can say is that if you agreed for whatever reason to do it, it was your choice to comply and no blame to anyone else.
Learn the lesson... you will never be able to change another person. If they do change as a result of your request, it is on them to blame themselves if it does not work out. Too high expectations of other people will kick yer arse until you really understand this.
