When a film's heroine innocently coughs, you know that two scenes later, at most, she'll be in an oxygen tent; when, a man bumps into a woman at the train station, you know that man will become the woman's lover and/or murderer. In everyday life, where we cough often and are always bumping into people, our daily actions rarely reverberate so lucidly. Once we love or hate someone, we can think bad and remember that first casual encounter. But what of all chance meetings that nothing ever comes of? While our bodies move ever forward on the time line, our minds continuously trace backward, seeking shape and meaning as deftly as any arrow seeking its mark.
