answer:Yes, I did. I once visited my best friend’s brother who was gay and living with his boyfriend. My best friend did not know that her brother was gay (he had been married and divorced). It was obvious to me, and I confirmed it with the guys. I then urged my friend’s brother to tell his sister. (I honestly thought she wouldn’t mind.) He told, and she was very upset. I think they were better for it in the long term, but it affected their relationship badly in the short term. It also affected my friendship with her badly, as she got angry at me (kill the messenger urger). I wished very much that I had not intervened.
