I was at school, and...?

On one of my recent questions (http://answers.yahoo.com/question/index;_ylt=AtDPkTl6xFVBWS2Xmw3MkPfsy6IX;_ylv=3?qid=20071112151837AATBxRZ) some people told me to just laught with the kids when they laughed about seeing me naked. I did, and then they said that I liked being seen naked.So, when I was in the changing room in gym, I was near the door changing because I needed to get out early so I could get to my next cl on time, as it is very far away. So, as people left the changing room, and, respecting me, didn't open the door much so that no one would see me naked. When I was 100% naked and putting on my deoderant, someone oped the door all the way and nearly every boy in gym cl was there. About 1/5 of them were at the beach when my bikini fell off. So anyway, they were all laughing hysterically. I did my best to cover myself up, but they all just kept laughing. I started yelling at them and the gym teacher came over and she yelled at me, "Put some clothes on! I can't have you dancing around naked in my cl! You have detention, tomorrow, too!" How do I end this nightmare?
