I used to believe, although I don't now, that growing and growing up are analogous, that both are inevitable and uncontrollable processes. Now it seems to me that growing up is governed by the will, that one can choose to become an adult, but only at given moments. These moments come along fairly infrequently -during crises in relationships, for example, or when one has been given the chance to start afresh somewhere- and one can ignore them or seize them.
