My frnd Lenny was abused by a priest for CSA (I know..can u believe?), his father for psychotic physical violence.
We both "spoke the same language. In the first 20 years we were frnds we NEVER spoke of abuse, but we just KNEW. We each knew what the other went through.
There were others in my life as well. In the teen years, there were those who you just knew. There are things that victims will say, will do, will not say and not do. It seems as natural as teaming-up with other Americans whilst in Tanzania.
I'm "that guy."
