When people asked my dear friend, early in her widowhood, "How are you doing?" she would wryly reply "Waiting to die... and you?"
After all these years alone, I am not asked that question anymore, in the same way-- The assumption being that my grief is a thing of the past. Most people, I have noticed Just want to talk about themselves, anyway. But if asked, I might just say (with relish at their astonished look), "Waiting to die... and you?"
