The best thing that has ever happened to this kid is being thrown out of pulik skools. Keep him out and it could change his life for the better a thousandfold.
IMHO It's not even about that. It's about the schools brainwashing and conditioning the kids. Now every kid at that school knows behavior like this will cause consequences.
What would happen if every kid in that school did the same thing at the same time? would they suspend them all?
