We’ve had these fights before, the ones in which the decision we make means a lot more than the thing we buy, or don’t buy. Take our car, for example. We almost divorced deciding whether to buy a car to fit five or six; in the dealership while our older boys climbed into and out of fresh trunks you drummed your hands on your pregnant belly and stared into backseats that couldn’t handle any more of us. When we took our shiny new five-seater home it spent its days on our corner, where we could watch it from our living room window, minding it through the hum of Philadelphia life as it stood resolutely through all Kensington’s comings and goings.
