“At the beginning of the twenty-first century, to feel alone or want to be alone is deeply unfashionable: to admit to feeling alone is to reject and betray others, as if they are not good company, and do not have entertaining, interesting lives of their own to distract us, and to actually seek to be alone is a radical act; to want to be alone is to refuse a certain kind of conversational hospitality and to turn to another door, and another kind of welcome, not necessarily defined by human vocabulary.”
