Obviously: the deluxe cheeseburger franchise. Apparently: Brooklyn. But actually: the initials of an obscure experimental prose writer of Punjabi/British origin. Author of: "Monsters I have Known": an essay on inter-racial romances that ends with the soulful but unkempt and aforementioned BK drowning her sorrows in short, skim milk lattes, even though it is a well-documented fact that too much coffee makes her impervious to omens and others signs that things are or are not going well. Which is no way to live. It's precarious, and does not necessarily lead to a marital outcome. But there you have it.
With a big sigh, BK flipped through the glossy pages of Cottage Living, even though it was was clear that the so-called cottages were really five bedroom annexes to an already established empire of primrose-yellow wallpapered mansions in places like Vermont and Southern California.
