girls just want to have fun

I found this photo in a park just after a week of rain, i doubt it had been there all week but nevertheless it has nice muddy stains all over it. Some of the girls in the photo look vaguely familiar too. One of them may be a friend of a friend or something like that but i am too scared to tell her that i have this image let alone have put it online. She is the one with the fake vampire teeth (that you cannot see in this particular scan) so i hope you understand why i am hesitant to bring up the subject with her.
