Also, and I hope this doesn’t need to be said: Don’t drink in your dorm anymore.
When I was in school, you only got in trouble if you didn’t invite the RA. 
But we had segregated floors and the maile RAs seemed more of the “party breed.”
I had a situation little over ten years ago where my dorm got raided and they confiscated a empty bottle collection, roommates sword,& other stuff that I shouldn’t discuss. Surprisingly we got almost a detention where we had to write essays stating repeatedly what not to do on campus lol. And we used to have way too many people in our dorms doing van wilder type of things. Just learn from it and either not do it again or be way more discreet.
