is that about me?

The classroom is silent. Silent for a moment. That light is flickering. Maybe it's a wiring problem. That pen is clicking, they are probably just bored. What's that knocking? Never mind maybe I just heard something else. Is that light really a camera? Is it taking pictures of me? No, no, I'm overreacting. That clicking, is that morse code? Are they sending a message to someone. What if that message is about me? Are they planning something? Oh God, they are going to kill me or something aren't they. No stop it. No they aren't. There it is. That knocking. It's the person they hired to do it isn't it? No, no, I'm being irrational. Just focus. What is the square root of 64? That's 8. Square root of 144? 12, easy. And what is the square root of 81, easy that's- what's that tapping. Are they tapping my chair? Is that a warning? Do they see that morse code too? I have to get out of here, I'm going to die. Am I shaking? I didn't even notice. See that's a sign something is actually wrong. I'm not just paranoid. Get me out of here.
