So everyone — including NPR! hey NPR! Welcome to the period party! — has been all about how 2015 has been the biggest year for menstruation since fourth grade, when I pretended to not be totally into that video they showed us in gym class. Cosmo said it and Buzzfeed said it and Hello Giggles said it and did I mention NPR? They all made lists about big moments in the menstrual news of 2015.
