Based on the excellent answer from @njuffa in the post Is it true that Albert Einstein was kicked out of high school due to his "peacefulness"? there is a quote from what the "home-room teacher" who said to Einstein:
Your presence alone ruins the respect I receive in class.
Why did the teacher say this to Einstein. What was the context or the situation? Did Einstein undermine the authority of the teacher in some way? Or did he expose the teacher's inability?
