for sympathy
I think what you state is only from your point of view. Most women and girls do not want to be forthcoming about their menses.
I never want anyone to know about my periods. Most girls don't.
I wasn't aware that they were!!!
i myself wouldn't care if they knew it or not at least when i snap on them they'll stop and think, her cycle must be on.
