Teachers are a very mixed bag. Some of them are delighted to see a student learning, in whatever way that learning may happen -- and some are just annoyed that the classroom's reality fails to match up perfectly with their lesson plans. If you're a nail that sticks up, some will try to uplift you further and others will angrily try to nail you down. (And most are somewhere in between.)

Your mom didn't get in trouble she just exposed something that the people with PhDs in Education don't want exposed.
