More of a respect-loop, but my world history teacher in high school would sit at his desk and all of us would chat or whatever until he was ready to start the lesson. Then, without saying a word, he would get up, walk to the front of the class, and sit on the stool there, and within seconds the classroom was silent with every student looking at him. The man never raised his voice (unless he was telling a story), and ultimately never needed to. He didn’t believe in homework, because he respected our time. He never talked down to anyone.

He got respect, behaved in a way that justified that respect, and got more respect. It was inspiring.
