my theory about the whole menstration/PMS deal is that women are just born cranky, and use 'it' as an excuse.
while younger, they get cranky (and cranky is a very mild euphemism here) and will blame it on one of three things:
1: she's getting 'it' in a few days 2: she's on 'it' or 3: she just got over 'it' a couple days ago and still cranky
when she gets older: #1 is: she hit menopause, so doesn't have 'it' anymore, and that makes her cranky -all- the time
Only conclusion for a sensible man to reach is that they just like to be cranky, and 'it' gives them the excuse.
before the older girls grew up and married off, we had the wife, three girls, myself and two boys in the house. the girls had 'it' all within a two week time frame. Call us cowards if you want, but if we saw a box of pads or tampons come into the house we planned fishing trips.
