All mobs are sitting in classroom, waiting for Herobrine to come.

Enderman was doing the bottle flip challenge with Creeper and Slime. Wither Skeleton, Entity 303, and Zombie Pigman were playing cards. Zombie Pigman wore his ninja looking balaclava. Like always. Ghast and Spider sat at their desks in silence. Skeleton was doing a prank for Herobrine, Zombie was watching his actions. Suddenly door swung open, it was Herobrine himself, and you.

"Ahem.. This is the new mob, and our new student.. Treat. Them. Respectfully. Understood?"

Herobrine said without much enthusiasm, but he was serious and stern, he moved over to teacher's desk. Some were looking at you curiously, and some just ignored you.

Wither Skeleton and Zombie Pigman did knew you. You lived close to their houses. Basically neighbors. And grew up with them for some time.
