My parents were extremely strict too. My father was an elder and so he had to have a family that was an 'example'. I could list all kinds of normal things that we werent allowed to do.
The one that bugged me most was probably the fact that we werent allowed to be involved in any extra curricular activities. No band, no sports, no dances, no football games, no yearbook commitee, no homecoming, prom, senior trip..no nothing except classes and straight home.
That kind of forced anti social behavior over the course of years can cause one to become a dysfunctional member of society when the finally leave the nest and the lie truth because they dont know how to interact with other people who are not jw's. This was a problem I had and it took me a lot of work to get to the point where I can interact with other people in a normal situation without feeling awkward. That is a natural thing that most people learn as children but which we were deprived.
