The man who started The Samaritans died in 2007, and I have seen today that a blue plaque will be put up in his town. The BBC article about him gives the reason he starred the charity:
^He attended the funeral of a 14-year-old girl and asked the undertaker why the girl was being buried in unconsecrated ground.
He was told she had killed herself because she had mistaken menstruation for a serious disease.^
Now, I'm in my 50s. My mother is in her 80s and referred to periods as "the curse", and called sanitary towels "fluffies", but at least she told me! My own dd is 12 and started her periods just over a year ago. We'd been talking about menstruation on and off since she was 9 or 9 . She told me when she stated, and we've had an open dialogue about it ever since. Good grief, I can't even imagine what would go through the mind of a young teenager who had no idea. I don't doubt that there are girls now who don't know either.
Thank you Dr Varah, and to feminism for beginning to lift the taboo for some girls, on some societies.
