So, your new roommates just arrived, and once they walk in, right off the bat, you can tell the 2 of them are probably guys you shouldn't mess with. That is, if they get mad, which they aren't right now, But you were still nervous. They don't seem to see you right away, and just walk past you, neither of them saying a word. Before they leave your view, one of them turns around, seemingly looking to see if anyone else is watching, and sees you. His eyes go wide for a bit. What do you do?
