i say "in the truth" on accident a lot. i notice that it's difficult to talk about Witness stuff with non JWs/ex-JW's because i rattle off words like "book study", "field service", "talk", "elder", "assembly", etc without even noticing it.
When I talk to a non-JW about the WTS I make sure I use all of their lingo and emphasize it... doing this helps people realize just how much of a closed cult the WTS is.
