Because HOH, some of us have experienced it firsthand, that's how! Are you aware that most child abuse takes place behind closed doors? The perps get away with it because they can, they are opportunists. The same parents that might be pillars of society- the BTK killer for example was high up in his church. The victims are often not believed. It could just be a bruise, but when you put the pieces together with a dysfunctional family, chances are it's alot more than just normal bruising.
Excellent! You made it!
Holdon, THIS lady is the person you should talk to.
