A guy calls a phone sex service but just wants to chat first.

(from The Ecco Anthology of Contemporary American Short Fiction)

At first you think you know where it’s going because it’s familiar territory: Marilyn just wants to get the call over with. John isn’t in the mood yet and wants to get too personal, get to know her. But he doesn’t end up being her husband, or a killer in the next room, and instead we have this tricky little role reversal where he’s finally ready to commence the business of the phone call but she’s opened up a little too much, exposed her true self. It’s pretty brilliant.
