My brother in law is like this, but if the shoe is on the other foot and you tell him how it is in the same fashion, he goes into meltdown, if you speak to people in a certain fashion, expect the same back.
I am with everyone else, dont breach the subject unless she wants to discuss it, if she does, just ask her if she would like to be spoken to in the same fashion, guess you wont change her and sounds like you like that no nonsense approach, lets face it, if you disagree with her its the dog house for you
