Forgiveness
In my experience, specifically the individual who can neither give nor accept a genuine remorseful apology one should be very, very weary of. In that, those same individuals are never, ever wrong. In these individuals forgiveness can not happen within or be given out either. This I believe is trauma that has turned dangerously pathological even in early onset. This growth; "not growth." Plants a strange seed that grows a cancer; a free radical of awareness and consciousness.
