This
thread is about menopause, but several times PMS was mentioned. PMS is an even more neglected subject than menopause, I think. And it can have such an important influence in relationships / families!
When I was a child I always was a little afraid for my mother's reactions, because sometimes she could become angry for very small things. In general she was a good mother, but I wasn't able to know in what mood she would be.
It was MUCH later she explained it to me, that it had to do with her periods. Then I could understand it, because I had PMS too, and I knew what it was because I read about it on the internet. But experiencing the inpredictable moods of my mother when I was a child already had its influence on our relationship (and probably more aspects).
Probably back in those days (50 / 60 years ago) doctors did not know much about those things. And even if someone knew about it, they would not talk about it with children. I did not even know what 'menstruation' was until I had it myself (at 11 y.o.). My parents thought that was the time to tell me about it. And they gave me a sex-education-booklet (for children). I think everything having to do with 'sex' wasn't a subject parents told their children much about. It was almost a taboo.
