We make plans, don’t we? Dinner plans, holiday plans, life plans. We don’t usually plan against death. Or, indeed, against the upsetting of our plans for ourselves. Plan Bs are also just more of the same—plans that will allow us to envision success or indulgence or celebration or growth in a particular direction. Some of us even have plan Cs and Ds. Few of us have the heart to plan permanent farewells to the people we love, or indeed, to our own recognisable selves.
