its about Molly and her magic Mp3 player... Love Hertz

You've made my day after a crappy weekend.
My vote's still for a more conventional couple, though. Thomas and Justine, tricksy-ness of JB notwithstanding, it's in an anthology called Starcrossed Lovers, and I can't imagine the editor would allow a story based on the unrequited love of Molly for electronics, hilarious though it would be. Can you think of any other couple that would fit the bill?
(Ok. Maybe Kincaid and Murphy-- but I thought that one was going to be called "Hawaii"?)
