There can be yet another angle on this problem. And you can't say there is never an excuse for not visiting a demented relative. My father lost most of his wits when he was 95, and had to be found a care home. My brother and I were most reluctant to visit him, because he had been an absolute beast to us all our lives, and was still capable of violence. He might have looked frail, but could lash out quite nastily with his walking stick or crutches when you weren't looking. All our lives he had utterly alienated his offspring with spite, meanness, violence, and every kind of harshness. He never changed, even in his last years. So tell me, why is it unforgivable not to visit him ?
