Unconscious dressing

Jon was dressed in a grey tank top and a tight pair of jeans whereas Sarah was dressed in a short sleeved blue shirt and black trousers. They stood there staring at each other, then looked down at their own clothes. They knew what they were wearing was wrong, but neither could find the incentive to object. "Huh," said Jon. "Yeah," said Sarah, "So...what now?" "Umm," replied Jon, "Figure out who we're supposed to be now? Maybe we should check Facebook? Maybe that'll give some clues?"
