When I was in fourth grade and was taught about menstruation, my classmates and I were each given a little booklet that explained about the menstrual cycle. This was in 1974.
I remember one passage in the booklet said to "Make a special effort with your grooming and personal hygiene on these days."
Today, I brushed my hair--at the bus stop. That's about it. Anything more than that, I just can't be bothered with, today.
I want to sleep.
