LOL - parents are absolutely the last to know when their child is lying.
Daddy's are so easily manipulated by daughters that it isn't even funny.
But tell a single truth that no one wants to hear and you'll be branded a liar for life.
Funny how things work, isn't it?
Not in these cases they are usually among the first to know. They might lie about the homework but it takes a lot of doing to make up a molestation. A parent with a good ear can pick up on truth real quick. BTW it happens much more than you think. Likely in your own family. What would you do if your daughter told your wife she had been molested? Laugh at her? No you see in general the perp follows a quirk ritual and THAT is the give away. The next kid can likely describe the exact same act. Their goal is to steal a childs innocence.
