"Hi jw friend, thanks so much for keeping me up to date on what's going on in the jw organization. I happened to join a forum (jehovahs-witness.com) and am sharing all of this information there.

"I feel really uncomfortable discussing religion with you. I am happy to keep in touch with you as a friend and discuss non-religious stuff. Thanks for respecting my wishes."
