Because believe it or not some of us dont get that....
Well, according to my psychology book, and some other science book I read in college, less than 8% of the statistically monitored women in the USA actually get the clinical version of PMS. It was also found in the study that women who do not have the hormonal imbalance that causes
real PMS often do act as if they were having PMS to take advantage of other people and then blame it on their "natural functions."
If you are a woman you do not want the clinical version of PMS, because not only is the mood terrible and prone to swininging, but depending on how the imbalance effects you, you could have serious plumbimg probelms, as one of my co-workers does. Unfortunately for me, she never gets tired of telling people (namely me) that she "had female problems last night, which were quite unpleaseant and kind of gross."
Anyway... When I am confronted by some woman who is mentally immature and trys to take advantage of me with that "PMS" behaviour BS I just ignore their demands and requests that they point to their crotch about. It may sound cruel to some, but in the truth of it, you can allmost allways recognise when a woman is having real PMS... and it's not the same as fake PMSers, that is for sure. I'd much rather get a problem solved like a civil adult then a subservient child to an even more childishly acting individual.
:-p
Peace!
