premise: As a medium haired brunette wearing a brown shirt leans forward and looks on, an auburn-haired woman in a gray shirt is laughing, her head reared back somewhat as she holds a blue infant outfit, its price tag hanging just below the woman's left hand. hypothesis: Two men are laughing at a story as they look at baseball mitts to purchase for their sons.
contradiction: At least one of the people is a woman. They are looking at infant outfits, not baseball mitts and not all babies are sons.
