Winston, I think that the punishment is fine. That was a LOT of alcohol and there would have been a lot of people doing who knows what, in your house. I believe that good parenting involves setting boundaries, giving advice, handing out punishment when the child does wrong, giving praise when deserved and leading by example.
Too many parents these days are busy trying to be friends with their kids. You are not their friends, you are their parents and your job is to raise your children into adults that function in society to the best of their ability, knowing right from wrong and acting appropriately. You can be friends later.
With mine, we used to get upset at the little stuff, but the big stuff is different. Whenever something large came, we would sit down and decided the best way forward. Many times my kids had a grounding that would remove all contact from their friends. They could go to school and training and their jobs, but nothing else. We also used to ban the use of the phone and internet.
One of my weapons in attempting to keep my kids occupied was involvement in sport and part-time jobs as soon as they were able. Because both Mum and Dad were also involved in the sport, they had to spend time with us, whether they liked it or not. This left little time to socialise without our knowing who they were with and (hopefully) what they were up to.
Like many teenage girls the rebellion started at age 13-14. Lil, always mature for her age, emerged early and recognised that many of her "friends" were pulling her down. She tried many times to remove such "friends" from her life, but they always slowly filtered back in. So, to move on with her life she decided that none of these people would ever have any influence in her life again.
She deleted everyone from her Facebook account. Removed the numbers from her mobile phone. Then moved to Melbourne. Drastic, I know. But she is a driven girl with ambitions and recognised that if she wanted to get anywhere in life she had to move in a different cirle, not just in her social life, but for a new skating coach too. She is doing that.
I feel that my job is complete. She is now a fuctioning adult, supporting herself and moving in the right direction. These days I can not only call her daughter, but friend also. I am proud of her.
