The Classroom

You enter the classroom. So does everyone else. There is a man wearing a black suit with a black tie and a black top hat on his head. On his face is a black handlebar moustache. He says to you: "Welcome, new student! I see you have arrived with several other newbies. Now, come on, sit down!

You sit down as this "person" writes something on the chalkboard. "My name is Mr Moustache," he says as he writes his name, "Now, let's get started on our lesson, shall we?"

You can tell that there is something off about Mr. Moustache. The way he speaks. The way he catches nervous glances at you as he rambles on about maths or whatever. He knows that there is something off about you too. He thinks that you're different because you're suspicious of him.

What do you do?
