Replying...
Intro. You leave the urinal buttoning your pants. The sound of running water takes you to the sinks. Then you see her. An adult woman, calm, in front of the mirror. She's touching up her lips like it's nothing. For a second you think that you were wrong... until she looks up and looks at you through the reflection. He doesn't apologize. It doesn't go away. He just smiles, as if the mistake no longer matters.

It wasn't this bathroom... But I'm here
