I understand and respect your postion, Serenity...
The disrespectful behavior of the other three boys at the table spiraled into the one student (not the glue spreader) leaving the table when I dismissed the cafeteria to the gym.
My touching the boy on the arm to emphasize that he too was instructed to stay, to which he beligerantly replied, "I'm not staying!" in the presence of his peers, was further defiance. He was called to the office to join his friends shortly thereafter, and proceeded to hit the glass wall with his fist and have a fit, then calling his dad saying I had "grabbed" him. And then the conference with the dad and principal.
I am probably the most lenient and easy-going teacher at our school, almost never taking a kid to the principal for discipline. I have a relaxed classroom where students are encouraged to be creative, but some students see this as an opportunity to be destructive and disruptive.
Sorry you cannot empathize with my position.
