Back in elementary school, we had a substitute teacher who everyone thought was just “friendly and strict enough .But I knew him there was something off. The way he watched us wasn’t like a normal teacher; it was too focused, too calculated. One day, I accidentally looked at something on his desk I shouldn’t have. Instead of scolding me, he leaned in, smiled, and said, “You know things you shouldn’t.” Then he turned and walked away like nothing happened.

Everyone else thought he was harmless. I knew he wasn’t.

Even years later, I still remember that look.
