Don't you know how to lie? Plan ahead of time and stay the night at a friend's house with more lenient parents.
15 is when I started drinking, I had the time of my life at that age. Don't miss out on the fun! Also try to be responsible, I lost a friend who was driving drunk. Also had a friend crash his bicycle and smashed his face into steel, he's got stitches going from one ear to his forehead and to his other ear. They had to peel off his skin to replace his nose.
