an unexpected gesture

I often ask myself what makes a story work, and what makes it hold up as a story, and I have decided that it is probably some action, some gesture of a character that is unlike any other in the story, one which indicates where the real heart of the story lies. This would have to be an action or a gesture which was both totally right and totally unexpected; it would have to be one that was both in character and beyond character; it would have to suggest both the world and eternity. – Flannery O’Connor
