No, it’s a parents duty to protect their child. If you have to stab someone you invited in, the damage has already started. This is already a trauma for the daughter, and it’s from someone the mother invited into the house.
For sure, she didn’t “Invite” a pedophile into her house.
He didn’t introduce himself by saying, “I’m a pedophile and I like your daughter.”
She says, “Oh, that’s nice come live w/ me?”
Hardly.
These pedophiles are cunning con artists....they gain your confidence first....then they do their dirty work.
