When I was 16, during my Year 11 Prom, my parents told me that I had to be home after Prom finished, by 1 in the morning, but instead I slept at my friends house, and didn't return home til the next afternoon. My mum was worried sick, and I got a right bollocking. I was then grounded for a week, but I snuck out for an after-party, anyway.
Will, judging by the things you have done, surprised you don't have an ASBO.
