The Briar family have an odd genetic condition called simply "The Weeps." It seems that some family members have their nervous system cross wired. What brings pleasure or humor becomes expressed as tears and sorrow. It's not that they don't find the joke funny, but their body expresses itself in tears rather than laughter. It's all the more ironic that the family is generally extremely well off and lives in a beautiful, peaceful town. Their lives are so good that sometimes they just fall on their knees weeping at the joy of it.
