I had some run-ins with my principal recently; he redirected me on three occasions.
One morning he passed me in the hall and said, “Hey, the lab door was unlocked this morning. You need to make sure it’s locked.”
The next day he said, “Aaron brought a can of soda pop into your room with his breakfast. You need to address that.”
The third day he said, “You weren’t at your assigned spot in the hall this morning. It’s important that the hallways are monitored.”
