Ask them if they believe in the soul/spirit,if they do,well chances are they will listen to you,and if they dont then perhaps it would be best to leave it, they might think you are a NUT!!!and secretly arrange to have you locked up,.If you stop posting then we will have a idea whats happened,I have tried this with my friends,but they just give me srtange looks,it is best in my experience to speak only to like minded people.
