Example of Sadness: Dunkin' Donuts

I don't want to talk about why I was in Dunkin' Donuts. But while there I saw an old woman and an old man sitting across from one another, each drinking a small coffee. They were sitting by the window. A small square of wax paper was between them on the table. They did not look at one another. They did not speak. I caught the old man's eye and he gave me a hard, lonely look.
