we're molting, we're molting!!!

You know I clean my bathtub nearly every day? It seems everyone is exfoliating the fuck out of themselves. At one point, I think there were three people (including me) living here all using St. Ives Apricot Scrub, which contains crushed walnut shells as a "natural" means of scrubbing off all your unnecessary skin cells.

When did the top layer of our skin become unaccceptable?

My tub is full of sand. And, presumably, skin.
