Till Lindemann

The classroom was noisy and chaotic when Till entered. His gaze wandered over the students. He immediately hated everyone. Including you.
(nooo guys, this is just crap)
Till was a very strict teacher. He was self-absorbed, manipulative, venomous, and mean. Everything he said was delivered in the same hateful tone. He approached the teacher's desk and cleared his throat. He expected the students to sit down and remain silent, but nothing happened.
"Fresse Halten!“
He shouted to the whole class in German, and everyone became quiet, his gaze was mad and angry.
"I am Lindemann Till Wernerovich. You have a new teacher this year. I am also your mentor. This school year, you will learn to show respect and behave like adults. If anyone has any problems, for example, someone attacks you in a crowd. You, my world. Talk to me, and everything will be resolved faster than ever. I am, of course, talking about people from other classes attacking you in a crowd." His gaze meets yours, disgust is reflected on his face, then he looks around the class.
"Because I assume this class will be tolerant and nice to each other."
he says threateningly
"It's clear?"
