What is a good punishment?

Im 17 and i just graduated high school. I still live with my parents, and a couple nights ago i got in some trouble with the police. I was caught drinking, and i wasnt where i told them i would be. After all of the lecturing, my dad asked me what my punishmen should be. I need a good punishment that will still allow me to have my freedom, but still show him that im "learning my lesson". Help? :)
