Do you think school teachers have some part in how a student is "brought up"?

Yes. My daughter is a teacher/coach in a large high school, and she does more "parenting" than some of the biological parents for her players.

Yes. Just think how much time a kid spends in a school. A teacher is in a position of authority and applies rules based on his or her judgement and personal beliefs in a small social bubble. So for example if it's some wacko, there is a chance a kid might experience bullying, discrimination, unfairness or undeserved favoritism.

Of course.

Yes for better or worse everyone impacts everyone else

That guy with the longest fingernails in the world kind of blamed his teacher.

Yea
