^ At the same time, guys can put all the blame on PMS/Pregnancy/Menopause......exempting themselves from the responsibility of asking themselves what their contribution to the might be.
Is your wife/mom/sister upset because she's PMS'ing.......or because you've been inconsiderate. And even if she were premenstrual......during that time......offenses could be taken more seriously.
It's way too easy to dump the blame on hormonal fluctuations. Sometimes that's partly the reason....other times it isn't at all. This goes for women and men.
