I learned, sadly, that my communication with my eldest son did not achieve its aim. He got to an age where all the values I tried to teach was rejected flat out as he partook of the things of this world. A dad was left to simple "be there" and offer support when needed.
Heh Junior that is sad and how painful for a parent. Fortunately or unfortunately depending on how we look at it, our children have their agency. In your case it is so difficult to watch them walk a path we know will do them little good from an eternal perspective, however we consistently communicate love through our actions and words.
