My parents didn't ban too much - I had posters on my wall and listened to pop music (this was in the 60s) mainly because they were so busy fighting they didn't have much time for us kids.
The only thing was - mixing with worldly people in any way at all was strictly forbidden. I could go to school with them, but I was the kid who had to sit alone in a classroom doing homework while the Xmas disco was on in the school hall.
I wasn't even allowed a phone call from a school friend. I remember once a girl saying she was going to phone me up about some homework we were doing and I was truly petrified because I knew my dad would go ballistic. So much so I sneaked down the hall while they were watching television and wedged a card in the phone so it would appear engaged if she rang.
To be honest, what a life! How could parents be so awful to us?
I never banned my kids from anything. I got into a shed load of trouble with a pioneer sister because my son had a ghost busters car. She said I must throw it away. I didn't.
All my kids have grown up into kind, well-rounded young men and I couldn't be more proud of them.
