People can be overly protective and careless at the same time when it comes to their kids.
Overly protective cos they fail to provide them with adequate education on sexual related topics and lurking predators, and careless in trusting anyone and everyone being with their kids.
In fact I know of a girl who was abused by a uncle and the saddest thing was her parents chose to keep sending her time and again with this man, never bothering to check why their daughter appeared disturbed by him!
