The characters that recur to me include dejected daughters, demeaning mothers, distant fathers, rivaling siblings, and so many incarnations of romantic love. These are the personal relationships in which I lack of closure. But in my writing, I have made very few strong or bitter friendships.
Perhaps this is not an oversight but an indication of fulfillment. I need not ask questions to which I already have answers. I have been blessed in my friends. So I do not have the impulse to vicariously explore or explain the nature of friendship.
