IF by some STRANGE (and slim) chance this actually happened:
1) Get off the Intarweb
2) Go to an authority figure. Perhaps one of the kid's teachers, or school counselor or youth worker.
3) Stay off the Intarweb with your friend's traumatic life.
4) Make sure an actual adult takes charge of the situation. If he pisses his pants every time he sees a man, take him to a female.
Now, that isn't so hard, is it? If you cared about your friend you would stop posting this shit here and take him to someone who will believe him. If you keep trying to tell us, we'll have to assume you are lying.
