You have gotten real sound advise, i wrote a letter to my 89 year old religious stepfather, took me many months to finally get the courage to tell him, what ever the outcome i would be releived.
I did it at dinner on a Friday evening, i handed him the letter and asked him to read it because i was too emotional to just tell him, he didn't really understand too well at first but i gave him the book True Selves to read, every week i would ask how he was doing with the book, finally he finished the book, He has really accepted me no strings attached.
