A bronzed woman on the train wears a t-shirt that reads “TGIF” across her chest. She looks at no one as she shimmies to a song on her iPod, occasionally taking a pull from a 20 oz bottle of Hawaiian Punch. Her appearance is youthful but her hair is grey. Either she went grey prematurely, or she dyed her hair, I think. I quickly realize I don’t care, and obviously she doesn’t either.
