It's just life

As Ray Porter watches Mirabelle walk away, he feels a loss. How is it possible, he thinks, to miss a woman he kept at a distance, so that when she was gone, he would not miss her? Only then does he realize how wanting part of her, and not all of her, had hurt them both, and how he cannot justify his actions, except that, well, it was life.

From the movie, Shopgirl.
