Some people are really nice, but can be emotional every once and a while, but others are evil and are probably trying to get your pity so they can get something from you. Then there are some girls who are in the middle.
Anton- The more I learn, the more I believe we think ourselves as human to be too separate from the animal kingdom. Humans *are* biology-based creatures who have chemical processes that create certain drives in us. This means that sometimes we are subject to our animal drives, women no less than men.
I read an interesting study that showed that (straight) women preferred more masculine male faces when they hit the height of their menstrual cycles (ovulation), and more effeminate male faces when they were at the low point of their cycles. Also, another recent study showed that women are more prone to migraine headaches because of hormonal fluctuations.
To be perfectly honest with you, I can tell you that sometimes (especially as a teen, new to the whole hormonal change thing) I have done/said things to males around me that felt out of my control. Like leading them on and then changing course suddenly. Or staying with boyfriends that weren't the best for me, because I was downright horny. I'm not proud at all of some of my actions- and yet like I said, it didn't feel like I was consciously making these choices.
Hope that helps. Maybe this is why there were all those ancient warnings/traditions to stay away from menstruating women!
