Sad to see someone turn away from ur Lifestyle

I know someone whose parents live in White Tail. My friend and his sister (both now grown) were also nudists years ago. I lost touch with him and he recently got back in touch with me, after 18 years. Sadly, he has turned away from naturism because he is now Jehovah Witness. I can't understand how someone could go from being such a care-free person, loving nudism, to being totally against it. So Sad!
