Life is a question of nerves, and fibres, and slowly built-up cells in which thought hides itself and passion has its dreams. You may fancy yourself safe and think yourself strong. But a chance tone of colour in a room or a morning sky, a particular perfume that you had once loved and that brings subtle memories with it, a line from a forgotten poem that you had come across again, a cadence from a piece of music that you had ceased to play… I tell you, that it is on things like these that our lives depend.
