I wasn't born in. I got hooked in as a teenager. Was going through a tough time, wondered why we exist, why God wasn't doing anything to solve man's problems, if there was a true religion and, hey-presto, a JW classmate showed up with book that not only asked the questions I was asking but answered them too!
It all seemed to make perfect sense... although I do remember feeling VERY disappointed with the first meeting I attended - it was so boring! And I couldn't help marveling that all these grown people believed the earth would be a paradise again.... but that's also what made me keep studying: how could all these adults be wrong?! (Talk about naive!!!)
I left (many years later) when I went to the elders for help because I was secretly 'sinning' - the 'love' I was shown, and subsequent persecution and contempt, made me question if something was wrong in our branch. I just couldn't believe something was wrong with the WHOLE organisation. I took the humiliation and punishment but the way I'd been treated and the way the whole thing 'played out' eventually led me to take the first steps in my movement away from the 'Truth'.
