Anyone who was lucky enough to have supportive teachers growing up knows what a positive long-term impact they have on your life. But the opposite is true of bad teachers — the derisive and nasty offhand comments they make can stay with you well into adulthood.
Some teachers make blatantly hateful comments (like racism, ableism, classism, etc.), while others are more passive aggressive (like discouraging a student from applying to a "good" college and telling them to be "realistic").
Regardless, students tend to remember the horrible things teachers say looooong after graduation.
