My cousin( who was disfellowshipped many years ago) told me that he cannot speak to or come over to his grandfather's any longer.
He would stop by every month or so just to see his grandfather and grandmother. They are both in their 80's and not in the best of health.
My uncle who is still serving as an Elder would talk to his grandson only when his grandson would visit his house. Well,someone found out and snitched on my uncle. Now,he's being warned that if he continues to talk or meet his grandson he will loose his position as Elder.
My cousin said that the next time he sees his grandfather will be at his funeral.
