Well, google, you still go to meetings? Too bad.
Using a doubting/looking slant on your letter is good because anything you put in writing can come back to haunt you (and it has some people on this board). Asking an elder to keep something confidential is like asking a turtle to fly. I hope you typed it and didn't sign it with your name or anything. Deniability will more likely then.
Best to say nothing and attend as few meetings as you can. Does your wife insist on your attending meetings for there to be peace at home?
