Stop getting loud and drunk with your friends

Hey, I'm speaking from experience on both sides of this rudeness. I understand that you're catching up with your crew and getting a little tipsy and inappropriate as the night progresses, but keep the sorority chatter down to a minimum. The elderly couple sitting at the next table over doesn't need to know that you and your man just tried anal beads for the first time. Actually, nobody needs to know that.
