Juliia ultimately you are asking us parents our opinions on his parenting. There is no manual for parenting unfortunately. Everyone's parenting style is different and unique to how they grew up and experiences. His is being a cop and seeing how people mess up their lives. I think as a parent he his overstepping some. I would never drug test my kids unless warranted, and curfew is great if you are not to be trusted, can he back off some and show some trust to his daughter? Yes, for teens as parents we have to afford them some liberties so they can further develop into adults that can fend for their own. I understand where he is coming from but, at your age it is for me a give and take since you aren't an adult but, still live in my home. So I give you trust and a larger leash but, you have to maintain your grades or some trade-off. This way it becomes a 2 way street where my needs as a parent get fulfilled but, you get freedom. As to how you approach him with this prospect is a whole other issue. In anyway you would have to be delicate with it and approach on eggshells or you can just ride it out until you are on your own. I know that seems cruel maybe but, it is better than fighting him. You can always discuss it years from now and be like "dad you remember when?" Don't worry you don't have long to wait. Good luck!!!!!!
