They definitely have their own language...and it has been really difficult for me to stop using it. My boyfriend is mostly affected by this and he usually laughes at me lightheartedly if I say "the truth" and then I quickly fix it to "the lie". I am so used to calling it "the truth" and it is funny, because this shows my boyfriend and I just how weird the cult is because they change the meanings of words, and truly have their own language.
Interesting story: I was in Wal-mart with my now ex boyfriend and we ran into a friend of his from high school. Well there was just something weird about his language, and I got a weird feeling and I asked him right out if he was a Jehovahs Witness...and he was. Funny thing was...is he was talking about how he was drunk the other night...blablabla and obviously not adhering to bible principals (hypocrate) and I could STILL tell he was a JW. They definitely have their own language.
