Kids make stuff up?
Not when it comes to sexual molestation, especially very young children. I know of a fellow whose JDub wife left him for another JDub, took their two year old daughter, and less than one year later the poor little girl was waking up screaming from nightmares. When her dad asked why on one of his visitation weekends she described in perfect detail the type of sexual rape that the mom's Jdub boyfriend was forcing on the little girl.
When the dad confronted the eldurrs in the mom's town they used that same goddamned excuse. The girl makes up stories! Nothing ever done about it! Well except for the dad getting threatened with DF'ing if he pursued it. He did, and he was!
