My brother, after being encouraged by a friend, tried something ONCE. I told him to stuff it and locked myself in the bathroom. I told my parents. They cornered my brother. There was no repeat, and the friend was never over at our house again. The thing that amazes me is how dysfunctional families can get where either people feel theu cannot tell their parets, or parents refuse to take control of the situation and make sure it stops. In my brother's case, it was probably a fluke. He knows better, he never was interesed before, and he certainly lost the interest after this "friend" was no longer in conct with me. He knew he had stepped over the boundary and didn't go after me.
I can't help but wonder what was going on in the family besides this that made these boys feel that this behavior was "OK". Maybe if your brother had been caught earlier, Shangrala, he might never have gotten to the point he did. May your selfless love be rewarded. Huggs
