Grow up kid. Seriously, once you grow up a little more, you'll be responsible for balancing your own responsibilities and free time, and if you want to stay up or take a day off, you can do that. Until you can take care of yourself and afford to live on your own, or you're at school away from mom and dad (even then, you can't let games get in the way of doing well at school or you'll have consequences), you have to listen to your parents and take your punishment like a man.
