My friends and I had a great thing, we were the kids that all the old ladies and elders liked and trusted. Some were auxillary pioneers, some were doing the literature counter, we were all carrying mics, reading, answering a lot, and giving prayers.
Little did any of them know... We all had premarital sex, we all drank, everyone but me did drugs, and swore like sailors. We also did tons of mischief, got in fights with anybody, and our service time, was a joke. We had the "quiet knock" or "We need to do some RV's today" or "Let's work rural territory", then we'd meet up for donut break, and then go shopping or something.
Then most of us got married, then all got divorce, and guess what, we're all out. My crew were great, no one ever saw any of it coming. We all had each others back, and a couple of us, mastered how to fake out parents, elders, CO's, and old people, it was great.
My second crew that I hung out with after I came back at 23, were in their late teens and early 20's, they are all still in, but they are bigger drinkers and drug users than my group, and most of them aren't as good of fakes as the group I grew up with. They just don't put on an act at all, yet no one says anything to them. I'm working on the ones that I still talk to, trying to get them out, but they are too afraid of parental reprocussions still.
