Just watch the absolutely brilliant ad

This is a 2016 'content piece' (less of an advertisement in the traditional sense) from HelloFlo, the US-based feminine hygiene brand, in partnership with Kimberly-Chark's Kotex (tampons) and Poise (period pads).
The context is brilliant: periods are already referred to as 'Aunt Flo' in a few countries. So HelloFlo takes that idea literally and personifies periods as an elderly black woman!
The writing is incredibly nuanced , Nad hence fabulous!
Aunt Flo is seen through the eyes of a couple freaking out that Aunt Flo is late, a girl waiting to see Aunt Flo for the first time, and a middle-aged woman who is farewell ingredients Aunt Flo! Just replace 'Aunt Flo' with periods in the narrative.
The ending is fantastic too - Aunt Flo interrupts a couple when they are in the car getting ready for a romp .
Except for one direct line, 'Niagara Falls of blood coming from my vaginas, every other reference to periods is indirect and in sync with the personification narrative.
