Alcohol Policy Help!

Okay guys, I was stupid last night. I was in a dorm with a bunch of alcohol lying around and the inevitable happens, the RA shows up and busts the “party”. I wasn’t drinking anything and my friend(we were in his room) claimed compete responsibility and said he was the only one drinking(he was not). They took down our names and had us dump out the alcohol. In our school policy, it says that if you’re caught in possession you have to take a class, be put on probation, sign a statement, and then parents are notified…The last part scares me a lot. Is there a way I can prevent that? My parents will not be happy with that, even if I wasn’t drinking. Please help!!!
