I remember the first student I ever suspended. He was 13 years old.
It started off as a minimal disruption. He was stealing pencils from other students at his table. That turned into breaking pencils. Then, stealing homework.
Determined not to let him derail the entire class, I changed his seat. I went over to him, and quietly said, "Can you tell me what's up? I know you can behave better than this." He swore at me in two languages.
