graphic novel ideas

It is a city like Seattle in late fall, quite dreary and slightly rainy. A man takes his wife into an alley after having a loud argument with her. The argument continues for a minute or two until a slam against a garbage can, and by the screams of it, the wife is the one who fell.

H: God-fucking dammit! (his face in a repressed and disappointed expression, looking down on the ground)
W: Quiet, people are sleeping, most people don't approve of that kind of language, especially at night.
