What do you wish you knew back then?

I wish I would have known excatly how hard it would be to hear a child describe the abuse they suffered. NOTHING is worse then hearing a 4 yr old tell you about being sexually abused. The only thing I think of that is close to being as bad is hearing that the person who done it got away with it, because " He said he didn't do it, and they can't make him take a lie detector".
