[Ray]
"And um, just so you know, I'm sorry for the way I treated you."

[Mirabelle]
"I know."

[Ray Porter]
"I did love you."

[Narrator]
"As Ray Porter watches Mirabelle walk away he feels a loss. How is it possible, he thinks, to miss a woman whom 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 can not justify his actions, except that, well, it was life."
