Don’t yell. Ever. You’re keeping your message short, like one sentence. If you raise your voice, if you get combative, men quite literally tune it out. Men are told women are irrational, emotional, and impossible to deal with when they’re deep in their femininity. If a man hears a woman who is bitching at him he hears her as unintelligible noise like the adults on Charlie Brown cartoons. (Just look at the verb “bitching” for insight into society’s view of women)
Your words will be few and gently delivered. Short and sweet, in the truest sense.
