You are skipping your boring class, lounging around in an empty classroom. As you mess around with some chalk on the chalkboard, you hear someone walk into the tiled room. Mr. Fafnir lights a lantern in the classroom to see you.

“Hey! Aren’t you supposed to be in class, kid?”

He has a mischievous grin on his face. He knows you should be in class. You were caught red-handed.
