The only wingless Angel

Ten seconds later;

Instructor: "Well? What are you waiting for?"

Azzy: "No, I reject it."

Instructor: "Why?"

Azzy: "Just because I don't want to"

Instructor: "You have something to hide?"

Azzy: "What if I have? What if don't?"

Instructor: "If you have nothing to hide, show us your wings."

Azzy: "No, I don't want to."

Instructor: "I'm the class instructor here. You must listen to me."

Azzy: "Then, I will opt out of this course."

Instructor: "You would rather opt out of this course than show us your wings, huh? That is indeed suspicious."

Azzy: "No, I would rather opt out of this course than listen to your unreasonable commands. I'm not your servant."

Instructor: "Then, what will you do if other instructors will also ask you to show your wings? Will you opt out of their courses too?"

Azzy: "Yes, if they order me."

Instructor: "Indeed, it is as I suspected. You belonged to the royal family."
