be sure to keep helping those kids.if you dont there is nobody to.get help for them.it is hard emotionally and physically you may not want the children around yours,but be sure to speak with your child privately about the behaviour he is witnessing and why it is happening.10 years down the road you may see these children as young adults and that shy neglected boy just may help some lady across the street because he remembers that not all woman are mean...and everyone should be helpful
