Tell the truth about everything and do whatever the hell you want :) they make take away some of your things though. What's the worse that can happen? You're an adult and should have some freedom.
If they don't wanna give a little leniancy, take it all!
Wow and I thought my parents were stricts im your age and I have a bf but they only want me to go out once or twice a week:/ and I was thinking they treat me like that because im not independent. They always tell me as long as I live under their roof I have to follow their rules so I want to move out :/ Maybee you should get a job and try to move out they need to know and see your getting older and not a little girl anymore and you have to build your life now.
