My high school bully became my daughter’s science teacher — at her project night, she humiliated my child in front of everyone, so I finally put her in place.

Sometimes, a classroom conversation touches on a topic that resonates deeply with students. Perhaps it involves fairness, community responsibility, or helping others. When students feel personally connected to a subject, their reactions can be powerful.

And occasionally, those reactions ripple outward into the broader community.
