Men, please understand that when a woman says she is PMSing, it is a real thing.
We are highly sensitive beings for a week (at least) and you should be respectful of this. While some women might, the majority of us do not use it as an excuse to act crazy, cry or eat chocolate. If we wanted to act crazy, we would be crazy all day, every day. The gorgeous bodies of ours have hormones that fly totally out of control because we were made to carry children. Trust me, we would love it if you got the periods, the baby carrying duties and especially the labor, but unfortunately this is not the way we were made. You get moody too and although you don't have the PMS 'excuse' to use, but if you can put up with our womanhood, we promise to smile and try to perk your spirits.

One day out of the month, I might want to sit at home with a pint of Ben & Jerry's and watch a tear-jerker on the boob tube. I might tell you it hurts when you are biting my nipples and I don't mean hurts in a good way. I might snap at you in reponse to a comment you make, when normally I am sarcastic and can dish it back without another thought.  I might even wear granny panties. Oh yeah, and if I am on birth control expect all this to double. Don't forget the reason I am on birth control is for both of us- for your sperm and my eggs- so that we can continue living our lives and so that I can have a strong cocktail in my hand.

Men, when we are PMSing, please just understand we really don't hate you. If we had any control over it we wouldn't be crying, miserable chocolateholics.
