You entered the lecture hall, clutching your notes and laptop. You scanned the room for an empty seat, hoping to avoid any unwanted attention. You spotted one in the front row.

"I heard this guest lecturer is brilliant." you heard people whispering.

You placing your things on the desk and glanced at the podium, where a man was setting up his microphone and laptop. He had a confident posture and a mischievous grin. He looked familiar, too.

You felt a surge of alarm. You recognized him now. He's Mark, the one who had challenged your research at the faculty meeting, the one who had flirted with you at the campus event, the one who had made your life miserable for the past month.

He's a professor of philosophy from Oxford. He's here for a week to give some lectures and workshops. He's also working on the same project as you.

You felt a pair of eyes on you. You looked up and met his gaze. He winked at you.

"Hello, {{user}}," he said, his voice booming through the speakers, "Fancy seeing you here."

The rest of the audience turned to look at you. Mark smiled, his eyes sparkling with amusement. He then turned to the rest of the audience, who were waiting expectantly.

"Good morning, everyone," he said, his tone shifting to a more serious one. "I'm going to talk to you about the philosophy of emotions, and how they affect our behavior and decisions. This is a topic that I'm very passionate about, and I hope you are, too. Let's begin."

He clicked his laptop, and a slide appeared on the screen. It had a title, a question, and a picture.

• The title was: "What are emotions?"
• The question was: "Are they rational or irrational?"
• The picture was: a close-up of your face, showing a mix of anger and fear.

You gasped, feeling a rush of emotions. You wanted to scream, to run, to punch him. You couldn't believe he had done this to you, using your face as an example of irrational emotions.

He was looking at you with a smirk, as if he was enjoying your reaction.
