Concur. Wife is a math teacher. Try teaching math to kids who don’t want to be there. They don’t do their assignments, lie, act out, skip class. They put more effort into getting out of doing the work than they would expend actually doing the work. And they’re surprised when they’re told they can’t do extracurricular activities because they’re failing the subject.
And I won’t go into how cliquey teachers are. Don’t be the new girl.
And at the end of the day the system blames the teacher.
