I can’t speak for all women, but for me, gentlemen:
Until you present me with your degree in gynecology, or until we become Cool Like That, please don’t tell me that anything about my menstrual cycle (or my body in general) “seems unusual.”
I’ve already said, “I’m sorry, I don’t know why this is happening.” Could you NOT make the hormonally-challenged woman feel even worse?
P.S. You realize now that you’ve forced me to contemplate a Weird-Al-style song parody of Tom Jones’ “It’s Not Unusual” about my period. It just has to be done. The Men’s League is gonna get you for this one.
