"You go round to your girlfriend Sarah's house, but she doesn't answer. You find her keys under a rock. She failed at hiding it, as that was the only rock she had and it was right next to the door. Well, she failed at getting a good boyfriend, so we'll let her off about the rock thing.
You go in, and see her watching some vulgar japanese porn. You faint. The end."
That is my impression of the best story you can write.
