This part does not last long:

You work nights, so you can pick up the children after school, drive in the carpool line and talk to the teachers. I take the children to school in the mornings, while you are asleep, and we listen to books.

You work nights because of retirement benefits and orthodontic coverage. I work days because by now it is a career (though by default more than design).

You work nights, and I almost never see you.
